well I am an active mbin contributor and cannot confirm any of that. He never tried to contribute to lemmy as far as I know and trying to contribute to kbin is just a big disappointment (I've been there as well). As for the name, personally I don't care. It is just how it is and nowhere does it say "this is melroys bin" or something like that...
If you don't want to get involved that is fine, but the rumors around him are basically all false...
