I can tell you there is one that constantly plugs their services in any thread where someone asks for a hotel recommendation. They are a Virtuoso agent and do so by listing all the "benefits" of using one.

Except many, if not all, of those benefits are available through some premium credit cards which we already have.

While they are not directly saying "call me", it's in the profile listing andtheir signature (I believe) indicates they're an agent. It looks like they're just skirting on the edge of a TOS violation.
