i will say that the rule your quoted is a pretty common one across most pet sites. but usually it's with the intention to avoid people arguing publicly about their warnings or bans and the like.
but i completely agree with you, how are you supposed to know if your comments on those topics were ok or not? how are you supposed to know if you received any account 'strikes' or 'penalties' for the comments you made?
without even the moderators saying something, i have no idea how they expect people to know how to appropriately talk about certain subjects within the ToS.
very early on i had a comment of mine deleted with no word, nothing. i had to ask someone off site who i knew was a mod why i didn't get any kind of notification, and only after that did i finally get a message from Korvo, hours after my comment was deleted.
it's not that hard guys :(
