Sadly, it is forbidden to write about cheating in Forums.
Anyway, it'd be easier if you say his team name, so more people can report.
Well, clearly no.
As you said, this is indeed forbidden to accuse someone else of cheating in the forums. AND multiple reportings have no more effects than one report. Absolutely none.
Well, clearly yes.
As the rules said, it is forbidden to discuss about cheating and staff decisions, as you have demonstrated in the past
But don't worry, you are some kind of gods in BB Forums, as some of you can write whatever you want and be always right. No one can punish your multiples disrespects all around BB-World
