I think you may be stretching the truth there.
Nobody can get banned without solid proof. If suspicion is high enough then admins and vips look into it further.
As I understand you were banned for saying you had aimbots and would use them.
that alone can be considered a confession and can be used to ban.
If you look at our reports section you can see there are guidelines to follow in order to submit a proper report.
Any report not following or supplying the needed details are binned / ignored / informed of the missing information.
banning ingame is a slightly different story.
usually the players are banned on the spot or have their id and name taken down for future referance.
Any appeals can be made on the forum.
