Are we more concerned about a list intended to improve
Wikipedia than we
are about a list and forum used to harm Wikipedia?
There are things we can do about Wikipedia mailing lists and
Wikipedians. There is nothing (or, at least, very little) we can do
about Wikipedia Review. They are completely independent and can and
will do whatever they like. The only way we can do anything to stop
them is by legal action (I haven't investigated the matter closely
enough to know if they've done anything worthy of such action).
