HildrethPred is an idiot but can't see why this is an ETF2L issue.
They are prem players and represent the league. Not punishing public racism and public harassment gives the league a bad image and it makes the harassment problem worse. This also makes it harder for them (EDIT: ETF2L) to get sponsorships as I'm pretty sure sponsors are not happy about paying prize money to people who are publicly harassing other people and are proud of it.
