just ignore him. he will do crap with whatever you taught him (mapping you mean? or something else?) because even if he makes something amazing, people won't respect as much as somone like one of the staff at .map, because he will refuse to help n00bs and will probably have an arrogant attidude.
Anyway, he is a err.... (cmon m4rine, think of an alternative to offensive, rude language!) stupid person (bad insult, but it will do).
If you really want ot get at him, post about what he did on loads of forums, include his username and MSN and stuff, so no one will want to help him if he gets stuck in the future.
Don't let this stop you from helping other n00bs though; most I know will greatly appreciate any help, and acknowledge in the future who helped them.
Carry on being helpufl!
