Singlesnet Spams Twitter with Fake Accounts
Note: this spamming might not be done by SinglesNet internally but by one of their affiliates (the joys of allowing anyone to join your network)

This is older than social networks, in fact, it is almost as old as Craigslist from what I can remember. An old trick to do on Craigslist was to post on their personals of a girl looking for a guy and then BAM you have someone who is single, you know their location, potential profile info (if they send you a note with picture) and you can easily reply back with a “find me on one of these dating sites” canned responses.
I do not encourage the above mentioned practices, however, I will say they can be very effective. To be fair, my hat is off to the guy who pulled this off on Twitter because I was thinking about something very similar for the last two weeks
