Lots of toxic players in my games recently

I'm kind of shocked as to between Wednesday and Friday I have had at least 1 if not 2 toxic players on either the enemy team or my team. I occasionally get at least 1 within 5 to 10 games but these last few days I have had 1 to 2 per game. Just recently I had a Duo Kai'sa with a Thresh who both claimed they "carried the team". I tried to help the Kai'sa out as much as possible but the first gank I did (mind anyone reading this was a top vs an ) I missed one round of snowballs (was playing since I've been trying to get them to mastery 7) and instantly they start off with "get better", "can you aim your snowballs omfg". I tried to but with an Aatrox dashing and flashing around I was only able to get two rounds off on them. They then claimed I "Ks" "only come in for the kills" when I gave our ADC and Mid laners kills since those two were near by.

A couple games prior to this one I had an entire enemy team who would make puns off of my Jungler's name. Another game I played Kassadin Mid where I found out (only played him 2, maybe 3 times) that Singed can prevent Kassadin from ulting by using his goo. They would live with 10 hp and even trying to go after them I was unable to ult, so of course my Jungler and ADC both pinged "missing enemy" pings on me. (Kind of wish people would actually use the "missing enemy" ping right instead of trying to flame or harass a player)

Why are thre so many toxic people in each game all of a sudden????
