Well its not just the speed. It can be lane splits. Can be revving the bike to hard for nothing. Can be passing a car, it can even be leaning too far in a corner that they can fine you with reckless driving etc. Its all up to the mood of the copMy suggestion is, get familiar with how they judge the speed in the videos. Maybe it is not worth blurring the plates, but speedo instead. Should be easier. Also check if your software allows object tracking with blurring, should also make it a bit easier.
In the end, anyone can end up in someones dashcam and still get the fine.
