In the past
I have a vague memory that people talked about the map spamming glitch was fixed around Q2 2015 (a guess, I don't remember exactly when). After that, I Heard that it still was an issue, but I didn't find my self shot down after that by "speeders".
After seeing first post, I would now assume the incidents after that was that those who got run up didn't got run up by the map spam thing but rather they got attacked sideways (as from first post).
