FB is a "networking" scheme, networks of networks networked to ever more networks.
An interpenetrating matrix of "friends" "friending" other "friends" to many levels.
Do you know all these "friends" and their friends, etc. etc. to endless levels?
Can you imaging some nefarious hacker individual or darknet organization walking through these linked FB entities gathering personal information? That's a bit bigger deal than "Someone trying to log into your account on JohnDee.com Discussion Board with an incorrect password at least 5 times."
Are you sure you really want to be linked in such a chain?
Most FBers are not themselves evil, but largely far too innocent, trusting IT novices, with little awareness of internet security. Their vulnerabilities can easily be your vulnerabilities.
Incidentally, what's the benefit to
ME to "like" some FB entity? I don't get it.
