Best way to make members aware of someone ripping people off in trading section?

Thanks everyone..... not really sure what to do at this point. Im tearing apart a parts car that has a pair on them....ill just send them to my buddy. I wanted these, because I knew I wouldnt have a chance to get mine off for a little while.....well, a "little while" has passed. Ill wait a little longer, and hope to hear from him.....maybe until the end of the month, after that, ill "out him" and possibly go ahead and give negative seller feedback.....

Thanks again for all the help and comments.

I noticed someone made the comment, "hope you're feeling better", on his profile.

Perhaps he is incapacitated.
