I'm thinking they are being reaped because we post the links somewhere - heck most of us have them in our sigs - myself included. I see several that hit both my Christmas and Halloween pages and I just don't buy someone liking my Halloween page because there hasn't been any posting to it for probably a year... Dunno - just bugs me - so I'll keep deleting them for now. I've noticed the vast majority are women and most of them are filled with how well they're doing on a particular FB game... If it is some bot doing it some of the pages are somewhat extensive...
