Nobody gets a permanent ban on the first go-around, unless I guess there is some gross violations of a rule. But there is an appeal process, it's the contact us button.I believe one of the rules on The Verge is you cannot discuss or criticize the mods. They will drop you in a hole in the middle of the desert if you do that.
I don't really like the idea of permanent bans unless a letter, email or whatever is sent telling you the specific reasons you were banned and describing how your actions violated forum rules, along with an appeal process.
And here, no one is criticizing a mod, there is an open discussion about policies, and the mods/administrators have aired their viewpoints as well as a number of posters aired their viewpoints.
This isn't a court of law and this site allows for a wide range of expression and the site should be rated G for all audiences and somehow posters who feel aggrieved have to come to grips with what is being posted.
