In the screenshots we can see the spanish speakers players:
Pocaspulgas, Srwar, Aragondlt, Asthrael, Mikfilerr and Furukawa
Doing insults against russian players, so this is reason to mute or maybe ban if we consider that them do mention specificly the word "russians" (rusos).
Also, the player Kunni said:
"español de mierda"
Translation to english:
"Spanish of shit."
So, it's reason of mute or ban too.
I will not do the punishment, because I prefer that a russian GM decide, because I don't have the power to ban and maybe is necessary in this case.
Regards.
