Theo: Hi, I'm Theo, and I posted an answer to Perl Monks without getting the question.
Support Group: Hi, Theo!

As to what should be done: if the poster has a point that he feels is worth archiving, he can post it as a stand-alone node. Assuming others agree, the new node will get votes and the poster will gain standing, both in XP and the more important community recoginition.
I think communities remember people for their good contributions, except when someone insistently and repeatedly makes bad contributions.
