Riot officially doesn't give a fck about soft inters.
So some days ago I started a thread about Rito not punishing even obvious soft inters. I also submitted a ticket since the IFS is trash in this matter, after one day the support told me, that he really sees some problems with that game, yet he can not inform me about punishments. So far, everything looks okay, we know that the punishment for inting IF caught is at least 14 days.
And what not, the guy plays again. So now officially, picking Janna adc, following the toplaner trying to steal his farm, starting with boots only, and dying 10 times in a 18 min game is NOT PUNISHABLE. (Happened in a dia game, so not knowing what a "bottom" role is, is not a valid reason.)
This is how much Rito cares about intentional feeders. And this is not about "it's hard to detect", and not about "bad game", this is pure trolling officially accepted by Rito.
