In an enviroment like ours were we deal with media every day, if someone steps out of line everyone will hear about it before you yourself realise it. There is no point in the coder trahing his reputation, with systems like iTrader in use and just general chit chat around the Forum. But on the realism side, im sure it has happened, if I were you i would try and build realtionships with coders, or hire ones with a proven track record with clients (again use of iTrader).

@Derek, im not too sure you follow the point, its work on a PSD that is unique to their site, i dont think people like having copies of there site hanging around on others computers.
