I don't use itch io much because I don't play indie games much but I love commenting the thing is I cant even comment something I've found in a game's folder while people can comment malicious link spams in the same game.
Like what I've said I'm new to itch.io but this feature is probably the most broken thing I've ever seen. I'll probably wait 3-5 days until it was posted if not I'll create a ticket.
