I agree with DG. The OP likely flags prohibited items on ebay and craigslist. Keeping the interent safe from bad buys one flag at a time.
Yep, you caught me. Damn, what will I ever do with myself? Didn't your mother ever tell you what assuming does? And since we're assuming things I assume you probably still live with your mom, right?
I'll be honest I've flagged one add on armslist. Only reason I flagged it was because the person who placed it was unresponsive. I sent 2 emails and hadnt heard back in over a week. Although I did have a set of wheels flagged on Craigslist for no apparent reason. 2 billet specialties 15x12s nib for 300$ almost half price and I always respond.
