The closed prefix isn't used, so I checked the forums for similar things and I found this topic:
http://www.guildwarsguru.com/forum/e...t10482619.html
It got the prefix changed to closed a while back but it was opened again (still has closed prefix) around the same time the topic genius made got closed, it might be related.
To me it seems like a random hiccup that shouldn't happen but does, similar to the date problem.
@rushin: I don't think it would be a mods action, as far as I know they cant close topics in ventari without adding the prefix (can be wrong about that). The anti addbot thing might be the case, but doesn't that result in the topic/posts being deleted rather then closed?
