lol. It happens all the time. I don't count how many times I've had 'friends' request from promoters that I don't know. I can only assume this is through friends' lists. You need to accept that facebook is a networking thing, and is used a lot for promotion, which has good and bad consequences (i.e. sometimes it is actually useful to know of new events being organised). I tend to put anybody I don't actually know on limited profile, and publish very little personal things anyway.
