I became a Wikipedia editor not long after the 2nd version of the site, before they even had logins, IIRC.
I was banned from the site probably 7 years ago or so by a troll who collaborated with the admins. The review "process" was more like The Trial and the ban was quite terrible, because not only did they install some deep cookie in the browser, but they permabanned the IP address.
Wikipedia is gone. Whatever it even was, it is not now.
