from the rules page:
Cooperative alliances whereby one party posts about another so that product announcement rules can be circumvented are prohibited. If we see these kinds of relationships develop, we will consider the parties to represent one another, whether a financial relationship exists or not. In other words, if you consistently support a particular person or company, we will view you as a representative of that person or organization even if you're not currently on their payroll.Soooo, what sort of cooperation is behind this?
