If someone has admin or moderator status in the forum, it is likely they will get a nice amount of free Ts for their work done.

Along with years of playing, the manager could save up tens of thousands of greens easily, especially along with months, if not years, of tanking.

So building such a team and keeping at a certain level for long periods of time is well within the limits of what a manager could do. It is just that when other managers do get drawn with such a manager, it is very difficult to not feel extremely hard done by and also very easy to leave a bad taste to the rest when that admin staff is making use of all the his privilege + years of greens savings + serial tanking to manipulate in such a way for trophies. A tactically skilful manager with years of experience can still get half of the trophy count with heads-on competitions with the toughest oppositions.

Not illegal or wrong, but hardly any room for much respect even when winning with trebles every single season (Not that the manager is bothered anyway).
