Social Networks and SPAM!

I would assume that this is fairly centric to my lifestyle, but I am ready to remove myself from MySpace, Friendster, Tribe, et al because of the amount of SPAM that I am getting from FRIENDS!  Now, many of my friends are DJs, promoters, and club owners; hence the predominant amount of messages that I receive through these services are promoting some type of event.  It just drives me nuts that I get the same promotion through mailing lists, social networks, direct e-mails, and rss that I am subscribed to.  Argh!  I get it!  You are throwing another party.  Got it.  In fact, I got it 50 times.  Argh!  If you haven't taken notice, I am not going out like I used to and the amount of e-harassment I get is inversely proportional to my desire to attend your event.  Argh!
