I understand why they don’t want links to GFR, they are a a clickbaity source with little real content, but banning you for questioning it is a bit far, a simple explanation would suffice (“hey, sorry you’re upset, here’s why it was removed, have a nice day” with a polite explanation of their stance of GFR and others like them) and we would all just say “oh ok, fair enough”, you would edit your post to say it was all good just a misunderstanding and we would all move on.
I know that on /r/startrek that source was in the automods blacklist so I can understand removing it, but the ban was way out of line when a conversation was possible and very, very easily resolved.
I also got a PM from that particular mod which rubs me the wrong way. if they want to explain their stance, they need to do it in a post to the whole community so we can talk about it, this place is supposed to offer a new start for a startrek community forum and that should start with a conversation between the users and the mods on how we all want it to work, not bans and pms to anyone who questions them.
