- to catch spammers early, increase visibility of changes. One way: get
at least one active subscriber on each wiki, or subscribe them all to a
big wiki changes list, perhaps funnel that to a script that checks for
too many urls..
- reduce the number of writable wikis. There are too many poky corners
to monitor. Perhaps some old ones can be deleted or mothballed in
- upgrade to current Zwiki. There is a banned_links feature, whereby if
you receive a mail-out containing spam links, you send it back to
spam at ..., which adds the urls to a banned list preventing future edits
containing those urls.
- swiftly revoke membership of spammers
- if spammers are joining a lot - though I think that's unusual -
impose a 24 hour delay or human approval step on member registration ?
- increase visibility of IP addresses of recent editors and joiners, and
set things up so it's easy to block them temporarily.
- possible blunt technological fix: hack Zwiki's edit() method
to reject any edit containing a url. Especially from a member account
less than one week old.
