I was talking with bitcointanner yesterday here is a quote from a pm

He also said he has a $100 AGC in another pm

I wonder if its the same user?

Jennak... Bitcointanner... This newbie user= the same guy.
Be careful.

How do you know they're all the same user? Post evidence if you have it to warn others.
