But nowadays people are riding bikes and making money by posting social media videos, I know posting social media videos is a different thing, but they are making videos of their driving, some are dancing while driving bikes, some are racing, some are throwing some lines at girl bikers, etc. etc. and making videos of themselves posting on Instagram and getting promotions.
You could argue that they're using them as a side job or even their main job at that point, so it's not really a hobby anymore. I believe some people consider a hobby to be an activity that you like to do in your spare time with no expectation of making a profit or anything, so there's a chance your hobby turns into a job when you make money from it. By this definition, traveling/posting on social media/etc to earn money is no longer a hobby, it's a job. It's not like people always hate their job anyway. I don't really mind whether people call their mining activity a hobby or a side gig, as long as they explain it clearly.
