olkah is a russian miner that was banned from telegram after trolling and speaking russian in the english chat after telling him million times that only English was allowed, so he is pissed off probably.

I remember one day he asked million times in telegram in 30 minutes saying that windows wallet wasn't working after that he left the group and said that the project was dead, the next day he came back to ask new things, probably he figured out how making it working lol
