What kind of experiences?
AM not telling me about lead caps, not telling me when offers go down, offers expiring right after my AM tells me to start them, i spend tons of time optimizing and $ on LP design, Misplaced conversion pixels on advertiser pages that screw with conversions (they took back $2000 from me on a compaign b/c advertiser had pixel misplaced on a zip submit), payout delays (waited 2.5 months for about $3k), Promises to get me on bi-weekly's but no delivery.
....all sorts of stuff....
i just Use CX and Hydra now...
