Blocking system with matchmaking

I propose that the ranked matchmaking algorithm be modified to include individual players' block lists. When playing ranked sometimes you report and or block players due to their in game behavior, however this only seems to affect the ability to read chat messages from the blocked player. I understand the current meta is to simply wait a few minutes to queue up, but in the case of a league promotion series and re-queuing with a blocked/reported player dodging the queue results in a penalty. I suggest removing the penalty when dodging a queue when a player on your team is in your blocklist as a simple solution. A technical solution would be to create a two column relational table from every user's block list and either post process the queue algorithm or incorporate the table into the sorting algorithm itself. EDIT: Did some other reading on the board about this, perhaps limit the number of players allowed in a block list to mitigate abuse.
