I guess something that has always concerned me with Facebook is security.
It’s always bothered me here, for example, that Coin Acquisition of the Week is unprotected, it’s not even in the Members’ section, and is basically a great big ‘hello’ to all the world that there are valuables around if they can only work out where you live (this is a little more challenging on a forum, I know, and some of us bank/alternatively store collections…but not everyone)? However, with Facebook that risk is multiplied near-infinitely, I’d say, with ill-considered page profiles making it very easy to track individuals down, almost to their door in some cases. With FB you can, in many cases, quickly find out where people regularly drink/eat, what they drive, where they work, etc. all within a few seconds…I guess this would be a major consideration of mine re FB coin groups!
