I'm not sure if I've ben ddosed but I know I've played against some people that were clearly cheating, Being Shot quite literally from across the map with a shotgun and getting headshot and shooting someone 10 times in the head and their health not going down 1 iota is clearly fishy, I don't mind going against truly skilled people but the cheaters ruin the fun and any learning I might get from the more skilled players is completely gone.
