Being Matched Again with Someone You've Reported

I normally write large wall of text posts, but I'm honestly too tired to right now.

There needs to be some sort of system in place where you can't be re-matched with someone you've reported.Not only have I seen a few things on the boards, but I'm currently sitting on a half hour ban because I got a game with a really toxic Shen player who blames everyone if anything goes wrong, reported him, queued again and got him again in my party (once again Shen, seeing as last game we lost and I suspected, hey maybe it'll be better.... it wasn't), reported him, and when I queued the third time, he showed up in my party AGAIN, so I warned my party members and said I would do the honorable thing and dodge so they didn't have to play with him.

Wasn't expecting to get sent straight from 0 to a 30 minute ban from games for trying to avoid a toxic player I'd reported twice in two games. I really want to enjoy this new queue since Teambuilder is gone, but I suppose I'll just give up on trying ranked for now since things seem to be incredibly toxic at the moment. (I've lost 6 games out of 8... know how many of those had afk's or trolls/feeders? 5 of them.)

Has anyone else been having problems like this lately? I don't know if it's just the new queue or the client in general.
