If you create or reblog ANY fandom content, monetizing your blog is illegal.

Let me say that again.

If you create or reblog any fandom content, monetizing your blog is illegal.

There is a reason why AO3 doesn't allow you to put a ko-fi or Patreon in the notes, and it is because they cannot legally protect you if you do that shit. You will get sued, you will lose.

I'm lucky to be part of a community now where the creators of the thing are so encouraging and supportive of fan artists, and I don't think they would be likely to take legal action. But a few years ago I was in Marvel, which is owned by Disney. You better believe Disney will snap a cease and desist on you so fast you'll be spinning. Same for anything owned by WB, Hulu, etc.
