but is it trusted? it says the guy is a moderator but again i've seen some mods go bad in the past so i wanna be sure.

It's Reddit. It's absolutely impossible to call something 100% safe or not.

Is it safe? Probably. Can we promise that it is? Not really.

Oh yeah, I've had friends buy from him and they received their key that same day or the next day.  He's legit.

As long as you buy from a trusted seller you should be fine.
