Cheaters - spoil the joy and fairness of the game

[robyar]

@Sillybq, cheers, appreciate your answer. To be honest I was hoping for similar feedback as yours.
In my case, the guy managed somehow to get both of his teams in the same league (probably due to location/time zone). Both of the teams are quite strong (1st place and 4th place). When the 4th place team is playing against other managers there is a strong player line-up achieving quite good results (even a draw against me). However when playing against his 1st placed team he loses 0-7 and 0-9, with a line-up of the 3rd reserves (weakest players available), spoiling both the competition's fair play and the top goalscorer competition results.
I doubt there would be a lot of managers around, happy to face a similar situation, which practically insures your cheating opponent a 6 points head-start/advantage even before the league started ( plus a 16 goal difference advantage)...
