This isn't a callout exactly, but a casual inquiry.
Just want to inquire on why you guys removed Tambourine-Man's article from the front page? Is there an official statement on this whole incident to read?
Not criticizing the removal as I smelled a rat too, but I just thought I mention this saying because it would have worked better, "Give them enough rope to hang themselves with".
What I mean is, let him appear as if he's strengthening his position by posting his pieces where in reality, you set up difficult well-timed questions/evidence against his claims and attempt to run a 'background check' on who he's connected to. Disproving his honest intention by revealing affiliation to Autism Speaks or to any person related to the organisation, would have given you guys better munition and solid justification to boot him. After all, you then could cite his conflict of interest, false impartiality and expose him as biased puppet.
It doesn't look as good for him when he's a biased puppet trying to accuse you of bias, see what I'm getting at?
BTW: I find it ironic he's trying to accuse members of AFF of sockpuppets/manipulating people on WP against him, when clearly he has a group of users praising his ass/harassing critics everywhere he goes as well.
