Why get annoyed? the guy has likely read the comments and likely wants to know where to support your other work. Instead of down-voting him you could just privately message him a link to where he can pay and then everyone is happy. He has a way to see what he wants, and you get more money. I guess its annoying to have thirsty guys post these comments over and over. But he said nothing offensive and you might as well jump on potential free money. (also the thirstier guys are big consumers of the adult film industry). Another good method if you dont want anyone to talk about your other works is to just use another account or just press the hide button on your other works for 24 hrs after a regular post (only if its really annoying to you and you want a solution) IDK just wanted to point out there are much better solutions then getting tons of trash comments over and over
