My take on it ... PM's can be manipulated, edited, taken out of context etc. I'm sceptical when someone says, "look what so and so just sent me" unless it's a close friend of mine, both on AND off the boards. There are exceptions to the rule, like the one posted in this thread, but if someone I know on the boards/computer only is trying to get me involved in some PM "thing" by posting it on the boards, then sorry, I really don't know them well enough to know if they've "played" with the PM or not, so I'm really not interested. It makes for some drama if you're bored, that's about it.
I almost sent one to someone yesterday, but decided against it because I really don't know the person I was sending it to and I really didn't know what they would do with the PM. I was only going to laugh with the person and tell the person about my experience, but I thought "Nah, better not", and erased it because you just never know ...
I do remember some PM drama years back that had me roaring though.

Two people that hated each other, both trying to pretend they would never be mean to anyone, posting ugly PM's they either both sent or both manipulated. I was bored, it was momentary excitement before the WM's saw it, that was it.
And ... I remember seeing a private message someone thought they were sending through PM, only to realize they were posting a new thread on the CB, not sending a PM. It only stayed up a few seconds, but I got to read it before she realized what she did and edited.

It truly was meant to be private!
