Unless you have a very good reason not to, or are publicly known anyway, there is really no need for you to use your real name or photo online.
Back in the 90s when i first discovered the internet, this was common knowledge. Nobody used their real name on forums or share personal information without considering the consequences. Those few who did were promptly told that's a bad idea.
It seems somehow we unlearned this, right when corporations started monetizing that information.
