it COULD be a bot post, if its a new user you will not see the post,
the mod i use to hide the un approved posts does not stop the feature regarding sending emails to subscribed topics, so ithers not really anyway to stop these emails except by un-subscribing from those topics..
I personally havent deleted any bot posts ina couple days.. what posts are you refering to by chance?
Jon have you deleted any bot posts recently?
OHHH WAIT!!!! is it sending you to http://www.our6thplanet.com
because i installed a new site at /FORUM that is getting bots daily... i'll delete it right now, its not in use, but you could be subscribed to the topics on that forum (it takes all this forums data and uses it there)
if it is that one i appologize for that, but i would liek to get to the bottom of it, did this start happening recently?
