Do you “like” things on Facebook? Spammers like things, too, and they’re using Facebook’s “Like” function to put their obnoxious schemes and shameless missives everywhere.
Facebook assumed they were doing Facebook Page administrators a favor when they added the option to “Use Facebook as Page.” This meant that customized Facebook pages could Like, post, and comment around the site just as regular profile users do.
It didn’t take long for spammers to realizes by using their page as a profile and “Liking” others’ pages, they could spread their message and elude the Facebook police.
