The only username you should use more than once is your real name.

You shouldn't use your real name on the internet.

For most people it doesn't matter much because there is many dupes.

Mine seems to be unique, which is a little scary.

There’s a few other people out there who use the same username as me, so I have had to come up with several other usernames.

Or use someone else’s real name. Like Abraham Lincoln’s.

Negative. Only use your real name.

I was 12-18 years old so I wasn't really thinking that way.

um, many people enjoy having a persistent online alter-ego, and some annoying people like to claim others when a service launches, just to be a dick.
