[OpenStack-Infra] Wiki.o.o sustaining spam attack

Hi all,


I'm sad to say that:

* spammers are back - 100-odd pages have gone in over the weekend
https://wiki.openstack.org/wiki/Special:NewPages

* Cleanup was ineffective, with many spam pages still existing on the 
wiki (scroll through the NewPages link above)



Regards,


Tom
