Well the relevant Joel threads seem to have been purged.
Anyway Joel was an I-MA who claimed to be a Political Science professor at Tufts University. After building up a reputation and some Atlasian elections he talked about running against Kerry in 2008 as a Republican because he thought an electoral campaign would be so fun. He got people egging him on, some people even started talking about designing him banners and a website. Alcon actually checked the university's directory and found there was no one with that name, he even called the university and asked about him, and was told there was no "Joel Mahoney" employed anywhere in the university. After this revelation Joel went on a bit of a trolling spree and left.
The exact same thing happened with my brother's guitar teacher, accept that he was pretending to be an adjunct music professor at FAU and was studying for the bar. After he missed three lessons and refuses to answer my mother’s calls, she did a little research and found out that he was really just a Marathon Music store clerk (not one of the franchisees, as he had told us) with a wild imagination.
