i haven't gotten a boobsquad popup from UM, and i doubt they'd have a porn popup like that. you ought to try running Ad Aware to see if you have any adware installed on your computer.
ok first of all. i was not looking at boobs. at least not at work.
secondly, ad aware just removed 197 objects from the computer, one of which was the old toolbar the guy before me had installed.
what i am thinking is that it would pick up on words on the pages i was viewing and therefore when it saw me reading our board where words like "fucking" get thrown around alot it might have assumed that i was interested in looking at porn and therefore boobsquad.com.
There has never been sanctioned popup advertising on UM...I'm guessing your computer has one of those spyware programs that uses certain words as triggers to redirect you to the parasite sites...
