If somebody WANTS to get to you, they will. It's enough to know your bike and what you look like. They can easily follow you home, you do vlogs at least once a week so it's enough to know ONE road you ride often and then the waiting game starts. Most vloggers have been on the same road multiple times on video. It's easy to pinpoint and with street view you don't even have to live in the same country.
No matter how much you try to randomize the streets you ride, you're going trough the same street to get to/from home.
It adds to the channel mistery not really knowing who's under the visor but it isn't even hard to get to you or your home based on the info you post on yt.
I get a lot of attention from everyone when I ride. That kinda makes me nervous about vlogging and to get known on my city and that's why I have an added layer of privacy on my channel, and that is, language. No local is going to watch my videos if they can't even understand what I'm saying.
It's kinda sad too because I have been trying to launch a vlog in spanish, just for the fun of it and to see the reaction. Latin motovloggers is something that the internet is lacking, but I don't do it because of safety reasons. Every week at least one bike gets stolen. And not only bikes. A fucking gang attacked a couple friends on a red light 2 months ago and they stole, at gunpoint, their van with 3 bikes inside.
It's common practice to steal bikes the way you saw on that brazilian video where the thief got shot. Sometimes they approach with 2 bikes to steal you. The difference here is that the police won't do anything.
