How did you miss the negative trust from awhile ago and the strong possibility of a bought or hacked account?
BTW, great job on trying to help a scammer scam others

I didn't see it was a scam, I guess I should stop being fooled by users, last time I loaned to a hacked account and I ended up loosing 50$, now this wastes my time. The owners of the email addresses I sent him will not be scammed since they aren't stupid guys. Xetsr don't say it is my fault Yelpguy is scammed, since that has nothing to do with the job I needed to do for him. I will send all the sellers an message that the users is a scammer and to not deal with him.
I think it's a big red flag when his reasoning for you to
get emails from reputable traders is just that he's lazy. Should this be the case, there's no point in why he can't simply offer trades to them - it takes the same amount of effort and has the same success rate. Having the email would help in no way lest there's an ulterior motive. Having a strong reputation would likely mean that you're active in the community, and thus would check frequently for messages regardless.
