I prefer to remain as anonymous as I can, even if I hit 100k subs, there won't be a "reveal" or what-not. The reason I choose to remain anonymous is because I'm a low profile person in real life, I don't need or want the "fame", I appreciate the support from those that view or sub to me, but I'm not in this to chase the fame-train. If I was, I'd be posting daily about anything regardless, and also jump on the viral wagon to get maximum reach. I agree that there can be creeps or haters on the Internet that try to stalk you, hence my preference. Even if I go for any events, I don't go around introducing myself as "TheSighBored" or pass around follow-me cards or etc. I just remain low key. Some have spotted me before, on the streets or at events, and I reward them with stickers (if I happen to have some), and then they will obviously finally know what I look like, though if they wanted to take a #selfie I would still request them to let me put my helmet back on for it. I don't just hand the stickers out randomly to anyone. Some have said putting a face to the name will boost your following, while some say being anonymous is cool, gives that mysterious feel about it. In my efforts to keep the anonymity, I separate my bike stuff from personal, I setup a FB page instead, and my Insta is only meant for bike stuff, nothing personal. Many have asked to do a reveal, and I have responded with "there's no need for me to do so", I don't see how showing my face helps in presenting the content I have.
Sorry for the long post.
