I sometimes have a wander and only realise in post that my plate is on show hahaI think the simplest thing to do is just to remember not to talk about anything relevant to the video while you stand behind the bike looking at the plate, then you won't need to edit it out later! Or if your getting beauty shots but don't want to show the plate throw a rag over it. Personally I won't show my plate just incase, there are people out there who will report you just to get their kicks these days unfortunatley! If they are determined they will find a way to inconvenience you but there's no reason to make it easier for them!
People will do anything out there, getting kicks from reporting people unfortunately
