If they do it just to be funny, or spoil your glory I will also get upset But tbh it the last 2 months I have probably flagged 6 rides. As they tend to do a mtb comp or criticall mass and leave the devices on. But only if you can clearly see it was like that. What I mean by clearly see(driving on the highway at speeds of exceeding 90 km/h, usually the avg is around 110. or they said so in the comments etc. If you knew you left ur device on, why uplaod it? Or upload but then just make it private. But tbh im more fased about if I improved my time(pr) than ahcieving a Kom, its nice competition though.
