Firstly, can I take the fact that you didn't respond to the first section I wrote to mean you now agree? i.e. that throwing games will actually lead to a lower end MMR rather than just a lower rate of increase.

It's possible I've goofed a bit somewhere, but I'm fairly sure my argument is sound. I'd be happy to hear your thoughts if you think otherwise.

Remember that there is conduct summary now. I see exactly how many reports I got from these people.

Seeing the number of reports over your last 25 games is not enough to narrow it down accurately (even with the updates every 10 games that allow you to eliminate things a bit further).

For example, it's entirely possible that in the particular games you linked in which you were heavily flamed, the people didn't even have any reports left (seems quite likely - trigger happy reporters are prone to running out). Then in a game you didn't think much of where you were a bit angry or rude, a support reported you without saying a word.

Note: I'm not saying this definitely happened, but until you can 100% rule things like this out, you can't know for sure when/why you were actually reported. Certainly not enough to conclude that picking out-of-meta heroes is punishable!
