It is fine to promote one's own sites or one's favorite sites in sigs. The thing is 99% of the time when a person joins a forum and then preaches about how great some product or service is, they have a vested interest in said product or service. When they post about the product of service and then add it to their sig, it is nearly a 100% certainty it is a spam post.
Virtually nobody runs around joining forums simply to post unsolicited testimonials for products they have no vested or economic interest in. This is why many forums do not allow new users to promote sites until they have established a little credibility and proven they won't simply post some spam and then disappear.
