I just added a very necessary "Criticism" section on Vaknin's wikipedia page:
http://en.wikipedia.org/wiki/Sam_Vaknin#Criticism
It would be awesome of you guys could expand it even more, or provide sources for its claims.
edit: I also want to apologize for what I said on the last pages. I've gone through quite a lot of self-criticism since then and am determined to change, now. But that's for another thread.
