I don't think it has something to do with stats or mass reports, because its easy to make some bots to over-flood random players with reports.
Since the last and preview update Blizzard scans the usage of the mini map to collect some information's, (maybe a new function is coming ?), right now i not figured out what the want to do with it but i will get it.
But i think they look if the user is only or 50% moving via mini map, this will not do any player or fool. In my eyes its a relay easy method to catch bots they use the mini map. Maybe already a lot of players get flagged by using this.
But this is not a fail from twinkie, as already said he not support it anymore so he also dont need to check anything. Bottign is always own risk and using a open source code without edit the signs increase it to 200%
