Main thing I ever see enforced is a loose concept of "scammer" with tags being applied to various users for various reasons which don't seem to be well documented in a conspicuous way / nowhere I've seen in forums explains the exact definition of scammer (comprehensively or otherwise)
I'm glad you don't see moderation. I hate it when moderation is intrusive on forums.
Like when the mods imposed their own ideologies in the sidebar of r/bitcoin? And refused to remove it even though a clear majority wants to get rid of them?
Yeah, I hate that too.
