As a publisher who has about 2m / day (mostly SE):
Advertising networks promising, let's say, $1.5 per k for popunders WW and you knowing that you can do about 1m / day, then somehow those networks only do 350k impressions after a few days. Most ad networks can't handle any real volume.
Ad networks allowing dog shit advertisers with legit malware / browser locking tech offers to get through that violate their own TOS/AUP, usually through a small broker that gladly accepts the $$.
Ad networks (perhaps unknowingly) promising the world to big sites with elaborate sales pitches then delivering nothing and ending up on that owner's blacklist. ;)
