Guaranteed Gains (GG)
A paid promotion where the promoter commits to bringing a specific number of new subscribers, at a price per subscriber.
Deals are usually closed in Telegram groups, measured with a tracking link and paid in instalments. The trap is measurement: free trial links can be reactivated by fans who were already subscribed, so a large share of reported "gains" are not new subscribers at all. Verify against the actual subscription date before paying.
SFS / S4S (shoutout for shoutout)
A free swap where two creators promote each other to their own audiences.
SFS works when both accounts are a similar size and share an audience profile; if one is much bigger, it is doing charity. Nobody guarantees a result, which is the main difference from a GG. It is the cheapest form of growth and the slowest.
Mass DM
A single message sent to an entire fan list at once, usually to sell a PPV or promote another creator.
It is the highest-converting promo format, because it reaches people who are already paying for content. It is also the fastest way to burn a list: sent too often, or written like an advert, fans stop opening messages and the account loses its main sales channel.
Shadowban
A silent restriction where your posts stop being shown to others but you are never told.
Common on Reddit and Instagram for accounts that promote adult content. The symptoms are traffic dropping to zero overnight while everything looks normal from inside the account. On Reddit you can check by logging out and searching your username. Recovery is rare, so the plan is prevention plus a warmed-up backup account.
Tracking link
A link generated inside OnlyFans that shows how many clicks and subscriptions came from one specific source.
One link per channel (Reddit, Instagram, each promoter) is the difference between knowing what works and guessing. It is also your defence in a paid promo: the measurement is yours, not the promoter's. Free to create, in your account settings.
