I'm noticing that some recent friend requests in Facebook that are obviously from fake accounts (recently joined, generic photos, 'about' geographically and ethnically incoherent or implausible) have 'likes' or 'groups' that include the Rick Steves pages among their likes/memberships, along with the usual high-click but coincidentally beginning with the same letter of the alphabet, etc.
I'm imagining that someone or some 'bot is now going through the list of people who have 'liked' RS posts and is trying to get them to be friends. I think they do this not for simple marketing purposes but as advance prep for some upcoming campaign, because having real friends makes a fake account harder to spot.
