Hi, if an admin is abusing their powers by protecting all pages on the wiki, keeping it "private", that certainly violates ToU because wikis are there for anyone to edit. You can contact Fandom Staff to report that.
Hey there! I'm an Admin on the Memenade Wiki and we need a few more editors to really get it up and running. I noticed that you joined earlier in the Wiki's lifetime, but I was wondering if you would still be interested in helping out. We would really aprreciate it!
