Our guild is apperantly death?

So today the user named Kenan has messaged me;
Everything was fine till it took a turn for the worst.







I did my best to be very respectful but there is a breaking point; accusing people of calling him things, saying lies, it affects the whole guild when someone likes this does these kinds of things. I don't know what to say or do...

These are up here for the members who were on at the time, seeing it all.

This is slightly concerning....
