I'm not "famous" but I have a web presence and a fan base because of my music. I'm a composer and recording artist. I've gotten airplay on various internet stations and was chosen as one of the top 100 artists on Aussie.com based in Brisbane Australia (at least once that I know of). Some SF members know about my website and my music. My music is on Amazon, Apple Music, Spotify and other streaming-download platforms as well as on You Tube. Because of my web presence I don't mix my screen name and real name on forums, except by private messages. Search engines use something called botnets. They crawl the internet and pick up tidbits of information about people. Sometimes they'll use quotes or include a "tidbit" that's attributed to the person but wasn't actually said by that person, but someone the person is affiliated with somehow. I use my real name on Facebook because unlike here on SF, I never engage in financial discussions or things that are too personal.
