Maybe it's because dodgy sites feel the need to "legitimatize" their sites more so than genuinely trustworthy sites do.

Frequently the people who speak most forcefully about how honest they are are the ones most likely to rip you off. "If a man speaks of his honor, make him pay cash." ~Lazarus Long (Robert A. Heinlein)

How many big sites have Truste or BBB seals?

In my opinion, listing a phone number will probably build more credibility than any number of seals.
