Riot flat out didnt ban a intentionally feeding troll despite screenshots of them admitting it
So last game i had a troll adc who played as khalista. This adc intentionally fed and died 11 times in a 16-minute game forcing, by the end everyone on my team was afk in the fountain. After the first few intentional feeds, she followed me to the jungle and just used E to steal as much as she could before going top and taking his cs and exp while dying. The khalista in-game and post-game admitted that she was intentionally feeding and trolling which i got screenshots of and sent to riot support just to see how they handle this sort of stuff and as it turns out they responded basically saying " sorry you had this happen to you we cant tell you what action we're taking"I assumed they would ban but couldn't share.
Skip forward to today, I check opgg 13 hours later 0/9 as Rakan with 3 tears of the goddess. The game after that is a 1/11 Braum who clearly went afk because they're at least 3 levels below everyone. So yeah, you can blatantly intentionally feed, get reported by everyone, have a ticket opened and repeat this 3 times without getting banned.
