Well, I'm back after 1 day.
This time I got scammed by a senior member.
Checked the security log and Password was changed after the deal.
Lost £197.
Looks like I'm going to go bust.
Goodbye cruel world.
EDIT: (as stated by omega)
Link to all screenshots. I can't believe it because it's my second time in 1 week.
And the password reset was after the deal :/
