State of the game

[Vidu]

And the 30 min mute given to me without warning by another mentor was justified why?

You werent excatly friendly, either - if you take the comment that basic percentage is something thats taught in primary school as offensive, why shouldnt someone else take offense by your comment "sad you are a mentor"? Why is it okay for you to tell them that they're a bad mentor, but not okay for them to comment that you're bad at math?

Maybe this is my personal perception but the whole conversation can be read with you being someone who wants to stire up trouble - complaining about missing your nodes, then starting an argument with other people in said chat etc. I could see this being viewed as someone who just wants to argue and/or b*tch around - even if this wasnt your intention (just how it might not have been the intention of the mentor to directly attack or insult you with his comment).
And in order to prevent the chat turning into a personal argument between the two of you, they removed you for a bit - unfair? Maybe. Probably. But each server can make up their own rules about whats okay in the Network and what isnt - and if your server doesnt want arguments, they can take action to prevent that. And if people viewed your comments as more problematic than the ones of the mentor, they can remove you - and not wanting to be rude: I can see reasons to remove either of you. You didnt come off as super friendly aswell as easly triggered - and if the mentors "humor" spoke to more people and fits the general atmosphere of Midgardsormrs NN better (maybe its a place with some light teasing?) then its you who gets removed.

Just as a sidenote: You have no "right" to be in said network - its part of the game, but its not like you pay a special fee to enter it or anything.
