Hi,
I guess you mean the website "onlyfans.com"?
We've never had support for this website at least I'm unable to find any traces of a formerly existing but deleted plugin.
Seems like a plugin for this website has been requested about 2 years ago (via private support tickets) and the ticket still exists:
If you can provide valid (premium?) logindata- and example URLs for this website, I might be able to help out
