Short answer
A promo sells fake or worthless subscribers when the new subs arrive fast but almost none of them spend, renew or reply. Watch for spikes of free trial subs that never convert, accounts with no history, auto-renew turned off in the first week and clicks that do not match subscribers. Before paying, ask for verifiable results, run a small test with your own tracking link and judge the promo by paying fans and their spend over 30 days.
Key points
- Subscriber and click counts are easy to inflate; paying fans and their spend over a fixed window are not.
- Classic red flags: a sudden spike with near zero spend, empty accounts, early auto-renew off and click to sub numbers that do not add up.
- Before paying, ask for verifiable past results, start with a small test buy and always use your own tracking link.
- Agree the measurement window in advance and judge the promo on paying fans, spend per fan and renewals.
- Keep a shared promoter list with who delivered, who did not and why, so the team never pays the same bad seller twice.
Why subscriber and click counts alone are misleading
Most paid promos are sold on volume: a shoutout to a page with a big following, a promise of hundreds of new subs, a screenshot of a link with thousands of clicks. Volume is the easiest thing to fake. Clicks can come from bots or click farms, and subscribers can come from throwaway accounts, people who grab any free trial they see, or fans who were never interested in the creator. None of that shows up as money.
On a free page or a free trial link, a subscriber costs nothing to create, so a count of new subs says very little about value. Even on a paid page, a sub who joins once at a discount and never returns adds one small payment and an extra name in the inbox for your chatters to work through. What matters is how many of those fans spend, how much they spend after joining and whether they renew. Judge every promo on that, and the fake ones become obvious within a few weeks.
Red flags in your data after a promo
You do not need special software to spot most bad promos. Compare the fans who arrived through the promo's link with the fans you normally get, and look for patterns that real interest does not produce. One flag alone is not proof, since free trial fans always convert less than paid ones, but several together are a strong signal.
- A spike of new subs within hours, followed by near zero tips, PPV purchases or replies.
- Many subs on a free trial link who let the trial expire without ever paying.
- Accounts with no profile picture, no name, no history and no messages, often created recently.
- Unsubscribes or auto-renew turned off within the first week, far more often than your usual fans.
- Clicks without subs: thousands of clicks and almost no subscribers, a typical sign of bot traffic.
- Subs without clicks: the promoter claims more subs than your link recorded, or credits fans who joined some other way.
Red flags in the promoter before you pay
Many problems are visible before any money changes hands. Look at the promoter's own social accounts: a follower count in the hundreds of thousands with a handful of likes and generic comments usually means bought followers. Engagement that comes in identical bursts, comments from accounts with no posts and audiences from countries that do not match the creator's market are also warning signs.
Be careful with promoters who guarantee a number of subscribers, refuse to use your link, ask you to use theirs, push for full payment up front for large packages or only show results as cropped screenshots. A serious promoter can usually point to recent clients, describe the audience they reach and accept a small first order. Pressure and secrecy are not proof of fraud, but they are a reason to test small or walk away.
What to do before paying
Ask for verifiable past results: not a screenshot of clicks, but references from creators or agencies you can contact, and ideally the paying fans those promos produced. Then buy small. A single shoutout or a short test is enough to see what kind of fans this promoter brings, and it limits what you lose if they turn out to be worthless.
Always create your own tracking link for the promo in the creator's OnlyFans settings, named with the promoter and date, so the numbers come from OnlyFans and not from the seller. Agree in writing what you are buying, when it runs and the window you will measure, for example 30 days after the post. If the promoter will not accept your link or any measurement at all, that tells you enough.
How to measure a promo after it runs
Once the window closes, take the list of fans who joined through the link and count three things. Paying fans: how many spent anything at all. Spend per fan: the net amount those fans generated in their first 30 days after joining, counted after the platform fee and refunds. Renewals: how many of them renewed or still had auto-renew on at the end of the window. Our guide on tracking links explains the calculation in more detail.
Compare cost per paying fan and payback time with your other promos, not with the promoter's claims. A hypothetical example: a $200 shoutout brings 150 subs but only 3 pay anything, while a $120 S4S with a smaller creator brings 40 subs and 9 paying fans. The first looks bigger, the second is clearly better. You can run these numbers with our free promo ROI calculator.
Keep a promoter blacklist and whitelist
Every promo you measure is information your team can reuse. Keep a simple shared list of promoters and partners with the date, price, link name, subs, paying fans, spend per fan in 30 days and a short verdict: repeat, renegotiate or never again. Add the reason, such as bot clicks or trial fans who never paid, so the decision still makes sense months later when someone else is buying promos.
Share the list between creators in an agency, because bad sellers tend to approach every account. Review it every quarter, since a good promoter's audience can wear out and a new one deserves a fair test. Never respond to a bad promo by buying fake engagement yourself: it breaks OnlyFans' rules, wastes money and can put the account at risk.
Where FansTracker fits
FansTracker is a desktop app for OnlyFans agencies and creators, not affiliated with OnlyFans. Today it gives you fan profiles with subscribed and expired segments and message counts, activity insights per creator over 7, 30 and 90 days, internal notes per fan and CSV export, which help you see whether the fans from a promo ever talk or stay subscribed. The free promo ROI calculator works without an account.
A promo tracker that syncs tracking and trial links, measures fan quality and revenue per promo and builds a promoter leaderboard from real synced results is in development, along with the earnings sync it depends on. Until it ships, revenue figures come from the creator's OnlyFans statistics and your own spreadsheet.
Step by step
- Check the promoter. Look for inflated followers, guarantees of subscriber numbers and refusal to share verifiable past results.
- Start with a small test. Buy a single shoutout or short test instead of a large package.
- Use your own tracking link. Create a link in the creator's OnlyFans settings named with the promoter and date, so the data comes from OnlyFans.
- Agree the window. Agree in writing what you buy, when it runs and that you will measure results over a fixed window such as 30 days.
- Measure paying fans. After the window, count paying fans, net spend per fan in 30 days and renewals, and look for the red flags.
- Update your promoter list. Record the result and verdict in a shared whitelist or blacklist before buying the next promo.
