It would be great if many of the games worked like that. Sadly, in my experience, you can report/block someone and then immediately be matched with them again. This is especially true in games like Heroes of the Storm which have smaller player bases.

Being able to block someone and not be matched with them again is also a great mechanism to dodge better players. If you have a hard time beating a particular player? Block/report them, avoid being matched with them, and have an easier time winning.
