Person to person transfers

[MicroBob]

anyone - Are PayPal transfers reverseable?
Thought someone said they were.

Doesn't this make doing such business with a new poster via PayPal significantly more risky?

Just want clarification on this.
Seems we have a lot of scammers on here. Nothing against the most recent poster of course whom I don't know.
Just curious about this aspect of player-to-player transfers.
