Today I was unable to browse the forum, after the 3rd link I would get redirected (without clicking adds) to a full screen add. Pressing "back" didn't work properly as the sneaky add providers put in 2 redirects at some points so you would need to press back very fast to acctually get back to the forum (only to get redirected again after the next link).
Since I was at work and unable to decently copy links I took screenshots of my history and the add showing up. I hope it helps, if really needed I could find out the full url though.
Sorry if the size is out of place, I'm not familiar with linking pictures on the forum.
I'm getting at least 4 video ads that autoplay with sound, its pretty annoying. I have a bunch of tabs open and it took me some time to find out from where the sound was coming (luckily the latest version of Opera places an icon in the tab from where sound is coming from) I think there's a couple more, one from I think it was Barbie that I didn't screencapped in time and another one that I don't remember what it was.
