Why am I getting so many griefers in my games?

Here is my match history for the last few games:

7552918956 l primal beast running alone and running into enemy alone, globally muted during game
7552902567 l pos 5 pudge abandon
7552860133 l mid necro rushes dagon ONLY, gets it at 9 mins with 4 deaths. result: 19-0 enchantress opponent on mid
7552767327 l long game, pos 5 grim plays very poorly, worthless items, then abandons
7550071221 w played as wd, lost of mistakes, played him like 5 times, team won
7549980733 w played as lion, same as above
7548787204 w 68 min game, pretty normal and close compared to that
7548731357 l 7-16 (lvl7 @10 mins vs lvl10 lc) mid np tping behind towers and feeding, vs 536 stack duel victory lc
7548485224 l pos 1 pl barely more nw than a support, dying uselessly a lot, lc afk deffensively farming triangle
7548416320 l everyone fed meepo, offlaner didnt know how to play his hero
7548356120 l cw pos 1, i wasn’t good either but he felt insanely useless and died a lot
7548301173 l pos 1 dude was straight out afk from the start

I had more or less (rather less) success before, but in the games I lost I there is always one lc mid rushing khanda, or someone who plays their hero for the first time (believe me, I can go on)

I get someone who griefs nearly every single game, and it makes impossible to have fun during games. Worst part is that I have to play the game till the end even if there is 0 chance of any play. What am I doing wrong? In the past there were multiple occurrences of having a really good winstreak, where my team won pretty hard, and I took a good part of it. Even if it was a loss, it was something to learn from, and I could blame myself for the mistakes I knew I made, and it was somewhat close. Then I got griefers for the next matches till I lost all of my advancements.

I seriously doubt that after having such a good winrates at 1.7k mmr I reach 2k, and the skill difference is that much that I have absolutely 0 chance to win, and suddenly everyone in my team plays insanely bad, or griefs. I get a ton of uncalibrated players who usually play awful in my team

I know that I’m possibly not better then everyone, but it always feels like I’m the only one in the team that knows how to play, and nearly always feel like that I was the best in my team. I know this sounds bad, but prove me otherwise, because at this point I have no idea what to do to stop this.
