Because both of them got a lot of power and points. So, cannot infract and zap also no use, hence to settle a score, it will be protracted and both sides cannot win and lose.
Tonychat has been known to infract and zap others to silence, but no effect on eErotica69, but I think eErotica69 is more laojiao than this Tonychat. Tonychat only appears towards the period of the crossover from sammyboyforum to 3in1kopitiam. eErotica69 is much earlier.
