Instagram is one of those sites, where all the content you see is either content from people you actually follow (so, friends & family, and not actual spammers), or is actual spam from instagram itself (instagram ads), where links (to advertised products) are of course allowed.
So yeah... only people who'd get the onlyfans links (or whatever other non-instagram-ad spam) would be the people actually following the onlyfans "creator" (or whatever other spammer), and those probably already know the onlyfans link too.
