For me, it's simple...
I have avoided chat rooms, (MSN, etc), like the plague since I first used the Internet, many years ago... ;)...!
In real life, I find that most people are rather unpleasant, and most of the time I have no wish to pass the time of day with them...

...!
I carefully choose who I want to speak to, from their general appearance, and attitude...which is not obvious on the Internet...

...!
As you get older, and wiser, you tend to be suspicious of other folks motives to talk/correspond with you...
...and that keeps you safe...

...!
Cheers all...!

There are lots of very unpleasant/unsavoury people out there...
Switch your brain on, before getting involved..
