z8 was already disabled some time ago.

I guess we need to take a random sample and see how many errors there are in
that sample.

Users are identified by their IP address.  New users start with a reputation
of 0.1 (or perhaps 0.2 - I can't remember).  If a user tags something that
has also been tagged by another user - and tags it identically - then their
reputation is increased.  I think the value for a tile is that of the user
with the highest reputation to have marked that tile.  I think there's a bit
more to it than that, but that's basically the idea.
