if I have something against this person, I always follow the rule, push the contact button, but it seems that before you react, this person will continue to make provocation.

And I really wonder why are you not acting on the abusive words Physics Tutor keep labelling against me, just because it is in our language that you don't understand.

If someone keep telling you that you're mother is a prostitute, will you be happy? This is what Physics Tutor keeps on mentioning ON BOARD! So please, act on it properly! Thank you!
