TL:DR: ESIC finished their investigation regarding HUNDEN and the accusations he made towards some players. All players -niko were innocent according to ESIC so ESIC punished niko, he needs to:
Attend at least two 30 min 1 on 1 education sessions with someone from ESIC
Do a 15-minute check in with the Commissioner every month for a minimum of six months to ensure he has understood and is complying with the ESIC Integrity Program and to offer him support for any issues he might be having in this respect.
And he also got a warning, if he fails to do the things written above he will face a 30 day ban which could be even longer.
I guess you will say: "Why did he get such a light punishment?" Well, ESIC added that niko have ADHD and Asperger's Syndrome , and to quote ESIC: "which ESIC was informed would "significantly impact his ability to know right from wrong, make values-based decisions on his own, and communicate effectively in a conventional way."
Sorry, but this is like the shortest TL:DR i could do, its so much info lol.
