But!
My point is - that account was not created yesterday, neither was the thread, and it gets bumped up frequently. We all know how strict the rules here are, and seeing that the thread is still up was the biggest legitimacy indicator for me. I'm 100% sure I was not the only one
That's where you are wrong, the staff here don't give a rats arse about people being scammed or scamming threads, they just ignore it.
It doesn't matter when a thread is created, that was your first mistake.
You need to look at all the indicators yourself, like threads being locked, self moderated threads, newbie posts, negative trust all of which your scammer has.
