Continuing Gael's work, I tried to expand the LocalBadContent list:


I wonder how useful this turns out to be in the end, this smells like an 
arms race... I doubt the additions cause problems to real pages, but if 
they do, some of them need to be reverted.

[Btw, shouldn't LocalBadContent editing be restricted to those in 
EditorGroup? And could my account PauliVirtanen be added in the group?]

Another thing is that there are apparently ca. 11600 pages in the 
Scipy.org wiki. I'd make a wild guess that at most ~500 of these are 
valid content; the rest is spam. I'm not sure if getting rid of the spam 
pages improves Moin's performance. 

Do we have any valid pages with CJK characters? Much of the spam seems 
Chinese, so mass-deleting at least this portion of it shouldn't be 
impossible to do, given Moin's database format.
