I can vouch that good Acai sites that are not these crappy blogs are getting hit just as hard. It seems they are targeting the niche as a whole and looks to me like any site promoting a free trial Acai/weight loss product through affiliate links (even redirected), is getting hit hard.
But they do seem to be taking a few weeks to go through all the accounts and nuke the weight loss campaigns. Whether this means they're doing it manually, or their auto algorithm is just taking a lot of time to analyze existing accounts I'm not sure. They do seem to be able to hit new campaigns in other accounts almost immediately so it may be automated. In which case this may just be a weight loss niche specific quality score factor that we need to find a way around...
