Those accounts don't come with trusted real world connections. I'd imagine playing it right people buying these accounts would get really high conversion rates on offers they try and push through them, given that people are likely to trust friends with accounts that have been used properly before and aren't just accounts with 5000 random friends that don't actually know the person (there seems to be a market for those as well).
