Yeah, quite a few of us have brought this up to them. TP actually owns AvaTraffic.
I believe they try to keep them clean, but monitoring all their advertisers would be a huge undertaking. They rely on publishers to let them know.
As for the ones for TP, there's no "account" to manage them in. They are in-house through TP's AvaTraffic account, so there's no way to block them.
Hopefully they will resolve this soon, we've considered migrating to another platform as well, but with needing a license for 100+ sites, it can become very expensive, very fast.
