Theres a comment button. But you know that already. Did you know however, that comments have a much more lentient character limit?
But really, I have no idea why you would complain, the comments move pretty fast and everything I posted is Terraria related... Fussy peoples.
Still, if you keep this up, people may mistake you for a spam bot. We may have to lock you in a cage and throw rocks at you. Lol
