removed onlyfans.com

Recently, @ThePornHelper raised an issue related to OnlyFans false negative. After going through the issue, I tried checking for some popular onlyfans creators on sherlock and as per the issue raised all of them were giving false negative.

So, I checked with the current method of checking the username availability. It the following API url:

`https://onlyfans.com/api2/v2/users/grandmasterchefjojo`

It returns a 400 error code and doesn't work at all.

Why it's happening? It requires a token be passed in the headers to for it to work.

After this, I tried using BurpSuite to find any other way to check availability and unfortunately there aren't any.

Even the wrong onlyfans.com/thisusernamedoesntexist777 URL also returns 200 in HTTP response.

So, it's better to remove OnlyFans from supported sites list and add it to removed_sites.json

Thanks.
