* Skeevy, pandering advertising
* Skeevy, pandering CEO

* Weak, script-bound CS
* Shoot first, ask questions later attitude to third party complaints (whether they be copyright based or otherwise)
* Their sponsorship of and carving out a fucking exemption for themselves on SOPA

Network Solutions seems positively angelic by comparison.
