I have screenshots of his comments, he doesn't know that I based my character on teenage me, but he does know that she's supposed to be a minor as he left a comment asking if "water came in beer cans" because my character was holding a can of soda. I commented along the lines with "she's a minor, so no"
One of the earliest creepy comments was a few updates after the "beer can" comment, he mentioned her hips and used the term "hubba," which I didn't understand what that had to do with the comic I posted. He then later acknowledged the he wondered if my character would be interested in him even though he's "twice her age" and later on he claimed that she's his "dream girl" which is really creepy because, like I said she's supposed to be a minor.
Sadly I'm unable to block anyone on that website as, there's literally no block option, you are actually supposed to delete comments or talk it over with the person before contacting the admins, you are only supposed to contact them if the user in question isn't listing to you and continuously harassing you. To me it's pretty odd that you can't just block someone on there, it makes me feel like I don't really want to upload on there anymore, but I don't really want to be chased off of a platform that I did enjoy just because someone decided to be creepy about one of my OCs.
Edit: I forgot to mention that I just deleted his creepy comments, I do have all the screenshots though, it probably wasn't a good idea to do that but I couldn't stand seeing the notifications in my inbox, as well as under my comics, I fear that if I just leave them up, it'll prompt him to comment like that more.
