Whether these rules are good or bad is an entirely different matter.
The issue isn't whether the rules are good or bad, the issue is that El No decreed that he was a freeze peach absolutist. If something is absolute there's no room for exceptions.
I didn't call them I cunt, I merely linked to someone who did
No. It's like El No saying that you can
absolutely call him naughty names, someone calls him a cunt, and El No throws a tantrum.
Actually this is even more ridiculous since El No decreed that accounts dedicated to promoting competitors would be banned. Honestly, I don't even know who "pg" is at this point and I couldn't possibly care less (presumably he's one of those Joe Rogaine types). However it's pretty clear that this twitter account was used to post all sorts of content. Even with a tweet about Mastodon, or two, or like twenty that means there are multiple reasons for that twitter account to exist. It is not dedicated to promoting Mastodon. This is just El No throwing a very expensive tantrum because his massive ego is bruised.
