Yes, and if you chose to do so, it's fine for your money. What effect does it have on the competitiveness of the leagues in general?
You're also probably one of those guys who leaves proposed trades on the books, unreplied to, or, if you deign to turn them down, never bother to email the proposing manager to give any rationale.
The more active the managers in the league are, the stronger the league. Of course it's your money and your business, but it is frustrating nonetheless that some people pop up only when it's draft time.
Or do you let the game manage that for you, too?
