That was one reason I don't even really have a Facebook. I didn't like the menial things of constant updates and people commenting on my "status", and I could see stuff like this happening down the line. I literally haven't checked my Facebook account (or the email address attached to it) in over a year. I wonder if people still try to communicate with me through it :P
Hearing about these pictures and videos of animal cruelty, though... I hate those ASPCA commercials on TV (make me feel just awful) and I doubt I would enjoy seeing something more graphic posted on the internet.
