Griefing with Tahm Kench

The pickup and carry mechanic with this champ has a massive potential for abuse as I unfortunately found out last night.

I was playing mid against a with no jungler and 3 bot ( ) the latter called adc and the former two spammed chat constantly and refused to take alternate lanes. Around 10 minutes or so into the match, comes running through the river into my lane with barely any health, being tailed by the enemy adc and jungler. I tried to help him and caught them with my q, but swooped in and took the kill.

In chat Tahm Kench said "trash lux u wnt 2 see troal i wshow u trol" (ad verbatim) then abandoned his lane after he revived and came with his butt (cloaca?) buddy to my lane.

He proceeded to use his W on me and carried me right in front of the entire enemy team, spat me out, then hightailed it out of there while used her ice wall behind me (presumably to try to block my escape or something).

He did this multiple times and I was unable to safely engage or escape each time. After that the enemy team called him out, to which he responded with more broken English, decided to play seriously after we lost an inhibitor turret, and eventually just threw the match.

People throwing games by purposely feeding or refusing to help their team is one thing. A mechanic that can potentially hinder allies from being able to play their own champion needs to be aggressively addressed before this sort of thing becomes more widespread and gives griefers a brand new powerful tool to ruin games.
