Has anyone had any luck marketing and selling their cards independently (ie on Facebook groups, other message boards, etc)? Would love to get more info on this.
I was considering it, even joined a couple of tradeline groups on FB to see what's going on. I decided against it because some of the people in those groups seemed shady, like they tried to sell CPNs (basically fake SSNs, so this is serious fraud). Then there was someone who said he added several AUs to one of his cards at the same time, then the card was shut for fraud down because one of his clients used a CPN.
As an individual seller, I can't validate my client's details 100% to exclude fraud and synthetic identities (though if there are ways to do these validations using publicly available web sites, or inexpensive subscription tools, I'm all ears).
Another concern about selling directly if you are more exposed to legal risks if someone tries to commit fraud and you add them. If you work with a tradeline broker, they take at least some of that risk and maybe even all of it (correct me if I'm wrong).
Btw some people even sell tradelines on Ebay. I haven't tried that either because of the concerns I mentioned.
