I've seen this happen many times, but this time I decided to get a screenshot of it. In a small box, facebook recommends that I add a friend because we have friends in common... or I get a direct friend request from someone I don't know. I click the profile to investigate and, indeed, we have several friends in common. But an instinct triggers that something isn't quite right.
Example 1 - Notice:
- New profile
- No personal information other than "Single"
- Only 17 friends
- All 17 friends are male
- Only 1 photo, with a focal point of breasts and eyes (maybe I should have titled this post "Why men are easy targets for spammers")
Example 2 - Notice:
- New profile
- No personal information
- Only 5 friends
- No friends in common
Occasionally, I will go ahead and accept a direct request even though I suspect it to be a fake spammer account. Once I have 'friend' access to see all wall posts, etc., and can confirm my suspicions, I then quickly delete the person. Partly I do this to be aware of what techniques people are using for their less-than-productive endeavors, and partly I do it because... I'm curious. ;)
My point is this: If 'common sense' were actually common, these spammers would have nobody to prey upon. That said, if something seems suspicious/odd/out of the ordinary on the WWW (in other words, if before the WWW you didn't have a lot of beautiful strangers calling you, wanting to be friends), then please... think before you click. At worst, you'll lose a minute or two of time to be sure -- at best, you could prevent crashing a PC and spreading trouble to all your friends.
