I could care less what people use for a list, but out of curiosity, what caused it to be crap?
Disconnected number ratio?
Too many wrong names listed as being the owner?
Other?
I bought them a list was supposed to have 100k contacts with emails, phone numbers etc. I knew something was supposed to be wrong (too much for 99 bucks) Well I started filtering the emails and less than 10% were good emails. I gave up! after filtering 500 I gave up. That's why I say they are crap. Specially because I spoke with them few times before making the transaction.
You don't have to agree, they might be good for you. They were not to my intent.
