Legit sick of these trolls

I looked at my match history, and I'm 100% serious, no exaggeration, 5 of my last 20 games had a legitimate troll in them. 25% of my matches. TWENTY FUCKING FIVE. Now, you may be thinking "bad isn't trolling." I know that. I mean trolling trolls. The kind that everyone knows they're trying to fuck up your game. The "not helping team, silent farming the jungle, no interaction" kind of people and the "hur dur suiciding because I have anger issues" kind of trolls. It's really fucking annoying and Riot, you gotta step up and deal with these degenerates. Here are some examples of why they were trolling

1. Mid dies to Fizz, runs in and dies over and over INTENTIONALLY. Not getting caught. Not being bad. Suiciding.
2. I take top tower and Darius doesn't want me to. AFK farms the jungle for the next 25 minutes.
3. Vayne decides 5 minutes in the game is over and AFK farms and refuses to group until about 35 minutes in. The game would have been easy if Vayne hadn't decided she didn't want to play. Riot, fix your shit. Legit this cost me several hours of time I could have spent ENJOYING LoL, but you let these people ruin others' matches anyway. I don't care too much about the LP because I know I'll climb if I deserve it ( currently climbing towards gold) but it's just a waste of time and needless frustration. Tl;dr too many legitimate trolls. Fix your shit, Riot. Step up and deal with these people. Side note: the amount of people raging at me for playing the game the way it's supposed to be played is appalling (I killed Yasuo top and Malphite got angry at me for not giving him the kill even though Malph died anyway and probably wouldn't have got it) This community is going to the shitter, was so much better a few seasons ago.
