Why is riot doing less to combat toxicity / Why no supp tickets for Toxic/Trolling players anymore?

Like most of you I have an afk/dc or troll in ~35-40% of my games, and I usually just use the report system, but every now and then you get someone who's an especially talented troll and manages to get under your skin, keeps pulling your strings to give you some hope they will stop or help you turn it around, baits masterfully, you know, all that good stuff, and like a really clever one keeps the chat going but never says anything offensive.

Now you know this guys not going to be caught by the system, and there's no path to escalate this anymore via a support ticket, the "Feedback option" now just points you at the forums..

So that's it really, the smart trolls now just get a free reign?

I presume this was Riot just being buried under tickets given how many trolls their are, I mean the stats I have for 800+ games is 16% of games have a troll, with another 20% having an afk or dc, So as incredibly bad asthe community is, they are now doing even less to clean it up?

Even if they wer'nt getting to all the tickets lodged, why give up? Aka every ban or reform helps, surely?
