If you put recruiting money on recruits wit no intention of signing them, just to mess with another user, that is against our fair-play agreement, and you may find yourself banned. We will review case by case and sometimes may issue a warning, but other times may end up banning the user.
The user you are griefing paid to play the game and no matter how much you don't like them, messing with the game they paid to play is not acceptable. With GD, ruining just one recruiting class can sometimes end the game for the user.
With all the improvements we would like to make to GD to make the game better, I find it ridiculous that I have to spend time addressing this issue. We are looking at putting out another smaller update in the next month or so and we will most likely add a limit as to the level of recruits you can go after, which might affect some people that legitimately drop down to find recruits, but we have to do this to prevent people from higher divisions ruining the game for other users. Sorry it's come to this point, but you can blame the people that thought it would be fun to ruin another person's game.
