I recently noticed a user that puts link to his telegram channel directly in the gallery title, in addition to posting even more links and asking for bitcoin donations in the uploader's comment.
I'm asking if it's against the rules, because I don't see anybody else doing that. To me it breaks the uniformity of site's style, and looks like a distracting ad.
All of those are allowed. You can consider blacklisting the uploader in your settings.
Advertising that is not allowed is posting incomplete works with a link to another site to get the full work.
