HI Pheonix.
My 2 cents worth. If what you say happened really happened, Pheonix

, and that you did it intentionally to test a theory, then you're onto something. Because you say it's happened before.
But then how to find the mystery copy cat? Or to find your mystery hacker?
I don't think there is a mystery hacker. Is there? Ask DR G? Suirely he'd know if his system has been hacked.
No, I don't think you've been hacked. That I think is the least plausible option. One that I'd refer to as last resort. And second last resort would be coincidence.
I'm thinking more along these lines.

hey! You need look no further than the person you PM'd to find your mystery hacker.
And now another 2 cents worth (off topic), to make it four cents.
Maybe instead of getting rid of guest option, Dr G should look at getting rid of the Pm option.

This would avoid all the behind the scenes gossip and discrediting and silly stirring each other up that goes on.
Why? Because I've experienced that same silly ignorant type of discrediting that your PM was doing about someone else here. I may even begin to wonder, was it me you were gossiping about?

No matter.
But the stuff you said about her, "if she had that many experiences she'd be 300 years old." Hey

people sometimes have said that about me, till they've gotten to know me. But then some of them are my friends now.

Cool. And thay feel so silly for thinking that. it is something to laugh about now, but at the time it's hurt me.
Yep, that's right. Some people who've said that about me, (cause I've done so much that most epople haven't) have gotten to know me,

and seen my photo albums, and met my longtime friends, yep, then it's different story.
What if the person you were discrediting is like me, and has had all those experiences? Then all you're doing is creating silly groundless suspicion and doubt with another poster. That's not nice. You have no proof. And by doing that, you're stirring the pot and creating silly mistrust in whoever you're PMing. That's a bit silly and childish. How do you know what she says isn't true?
If it happened to me, what you said about your PM's being repeated, I might try really hard (and it would be hard for me

) to try to first assume a coincidence.
But seeing as you say it's happened before

, then I'd have look at the very very obvious.
I'd say, and it's a bit of a laugh really, but it was your 'friend' you PM'd who did the lifting od your words, if it wasn't just coincidence. That is what seems the most obvious reason, to dumb old me anyway

.
And, another guess is your 'friend' has another identity she hasn't told you about.

And why that is so easy for me to believe is you seem to have quite a few 'guest' supporters, don't you?

So I already know you do have friends with 'guest' identities as well. And I'd guess, with the content of your message example you disclosed, you're just stirring up her up paranoia.
