Anyone who gets on freenode using the name zewb is automatically banned from #ubuntu and #debian. They've banned me constantly since early 2007 for trolling. The guys in #debian actually threatened to send irc logs to my ISP and have my service cancelled for harassment, because I kept going in under different proxies and DCCing the channel. Some of them tried to root my server, and failed miserably because only certain whitelisted IPs can ssh in.
I was also g-lined from freenode on several occasions for poking fun at Rob Levin and his fatal bicycle accident. I got g-lined for saying he should have worn a helmet, I got g-lined for asking why someone on disability would ride a bike in traffic, and most recently, I got g-lined for claiming to have seen Rob Levin at Freebird's Burritos in Houston, Texas.
And I also got banned from the PLA forums for trolling, and putting huge3.jpg in my sig.
