twenty years back already the original indology list had came down precisely by a simillar kind of attack in which Konrad Elst was already involved.

 This is roughly correct. Many times I have been "involved" in attacks, namely as the target of attack. Thus, I have been called "the scum of the earth" here. (By contrast, I myself have never called anyone that, and can't remember that level of abuse even in the heat of discussions.) Obviously in contravention of list rules, but nobody intervened, and nobody even expressed support, at least in public.
