I’ve got it too, sent a report about it last night (surely, surely it’s not supposed to be there? No right minded website would allow them out of choice, would they?).
I use frowned upon means to make the internet useable on the computer but that thing floating around all over the place (once you’ve accidentally clicked all the adverts that take ages to load and get taken to adserve.de or wherever it is because you’ve tried clicking a link to a thread but the ad then loads and jumps everything down the page) will probably stop me browsing STW away from the computer.
I’ve not weighed in on any of the advert threads before but this whatever it is is annoying.
