I don't usually object to recruiters and haven't had any major issues with them (one saying "I notice you have Linux, Apache, MySQL and PHP experience... what about LAMP, do you have any experience with that?" did make me laugh though!) but one did go too far and when they couldn't get hold of me, Googled my name, found my name on an info page for a club night I DJed at, called the promoter's number (who was a friend of mine) and told him he urgently needed to get hold of me regarding work. Needless to say both I and my friend were pretty p*ed off (he used the line "come on, I know the best people are hard to track down" as if that made it okay) and he didn't get the time of day from me!
