You’ve made yourself known to children, and those who know no better way to spend their time than on the internet. This sort of thing happens, but usually dies off after a week or so (provided you don’t provoke them further). My suggestion is to wait it out.

Wait underage users ARE allowed on Itch.io???

Wait, do you mean here in the main community, or in jam / game communities? It's true I'm sometimes slow to take action. But we don't have any power at all over games and jams; reports go to their respective owners. Site admins can get involved, but they're busy, and they have to find out there's a problem in the first place.

Edit: I renamed the topic to make the title more clear. I know people don't like it, so I try to avoid that, but it literally said just "hmm".
