Yo, nice to meet you.
I've been having a bot/scammer problem going on in a daily basis and it's been infuriating. Then I looked up on YouTube if anybody appears to be having the exact same issue until I watched your video. Even if their art offers were real, I would still decline, delete their comments, and block them. Might sound like paranoia, but it's the best thing to do to deal with people like that.
