While my account is public, I don’t get loads of random people following. Always people I know or know of. I don’t join big clubs with random people I don’t know though 😉
Something odd about bikes and people from far east. I’m on Google+ and on UK focused bike groups and there the majority of people who follow me are bike people from the far east.
We get that a bit with Facebook bike groups as well. Specific groups focused on a local area and people request to join from Russia and far east. Though usually there’s some hot babe in the profile.
I set privacy zones for house etc on Strava though not often I ride/track from home anyway. I also have removed the names of my bikes. Just generic ‘bike1’, ‘bike2’ kind of stuff now.
