Not difficult. Just like BOL, they hide behind it as if it's a tech issue. Pinnacle has had it figured out nearly a decade before the first iphone even existed.
BOL/BM do it on purpose, they probably snared 10k+ on that move from bettors tonight.
In the past I had it set as Accept only line changes in my favor, but it did not stop this from happening. I've since had it on DO NOT ACCEPT ANY CHANGE. Still screwed. I have probably lost 10k to this BS.
