Mine has been horrible the whole month but over the last two days I have gone in to the new ad block center to specifically block ads and accounts. Today it doubled! I had about 40% of the ads in there that were total CRAP. Chinese, Norwegian, latin,etc. I run a tobacco site and about 20% of the ads were how to quit smoking! ARGH! On the other plus side, now that I cleared out the crap NO ONE was clicking on, MORE good ads have come in to fill the empty slots!
