So anyway, update, the guy kept sending me more messages expressing his hate for Democrats, and people unemployed on welfare, along with some wild tangent about killing small birds. After I let him hang himself a bit, I confronted him with the fact that I knew he had a local pc shop in San Antonio, his name, and expressed interest in posting all of his comments on a nice few reviews for his business on Yelp and Google, etc.
He started back tracking and denying he had a shop, or anything to do with it. The computer shop in question is
http://www.asg-sa.com/. The stores full address is listed there, and they link directly to their ebay account, so it's kind of impossible for him to claim they are not related in any way. His ebay auctions even use the store logo and contact info in the background of the pictures he takes for his items.
Pointed all this out to him and asked one last time if he wanted to add any further comments about people of different race, the LGBT community, etc since he was on a hate train roll. I'm not sure if I will squeeze any more replies out of him now. To be honest I was even getting bored up till the part where he went into denial about the shop in San Antonio and all. Anyway, we will see...
