Grawp is the most persistent troll/sockpuppeteer in the history of RationalWiki. They're also known for having trolled Wikipedia. In their tenure, countless accounts have been made,
almost always with bizzare usernames. They are almost always banned immediately, but the sockpuppets keep coming. Community opposition to IP range bans, long-term IP bans, and checkuser has made them even harder to stop. They started in 2008 and continue to this day. They have so far not done anything actually harmful, but are really irritating.
