Where are you seeing these? I'm still using the old format and there's nothing like what people are complaining about that I can see.

Both above and below submissions in the ad space. They seem to be gone now, but they were pretty bad, and until I know for certain they're gone, I'm gunna keep adblocker on :/
I really hate to do it, but frankly, I really don't wanna see that kind of stuff on here... >.>
Stuff like this

Hopefully the outcry will smother that kind of crap. I read some updates and it said they are taking screenshots from people about particualarly egregious ads and have deleted some already. Maybe there's a chance of them scaling bck to something a bit less nasty.
Meanwhile I have yet to see one on my pages. *shrugs*
