Unless the local Rules violate ToU, no. Wikis are like countries. Each has its own set of laws/rules. When you "cross the borders" by going from one to another, you need to expect a different set of rules and familiarize yourself with them same as you need to know the difference of laws when you physically travel.
Now, the "undos almost every good edit"… that might be crossing a line into *private wiki*, which IS a ToU violation… contact Fandom Staff with links.
