wiki spam

[Christoph Hellwig <hch@xxxxxxxxxxxxx>]

I just had to delete dozends of link farm spam entries on the xfs.org.

This is getting a bit out of control, so I'm wondring what we can do
about it.

I wonder if it's reasonable only to hand out account if a user manually
contacts one of the admins.  I don't want the bar high, just proving
to be able to writing a human person mail basically.
