The bannable offenses for sprays are:
Porn (showing genitals except boobs)
Gore/war injured/dead people
Racist sprays
Nazi sprays
Advertising in spray
But as we got a sprayban system now it can be resolved that way, and as an admin was in-game you could have told her and she could have dealt with it.
We only ban people due to their spray if it's a heavy offense, this isn't and can maximum lead to a sprayban.
Good idea Cudi
Thanks for reporting the player anyway.
