I find it fun to make up names sometimes and it gives some people a “peace of mind”. There are many ways to find out the real name of someone, but a person using a pseudonym might feel it protects them. I choose to use one because it is a name I
prefer being called and it’s not very elaborate. I also think pseudonyms can also be stimulating to the imagination because people can think of very creative names. Many people use names other than their birth names. Some entertainers have stage
names and other people use their nicknames more than their real names. I find no problem with using pseudonyms overall. If you want to be professional, then it might be best to use your real name. Using a pseudonym and being professional
would most likely involve making your real name known, while establishing that you prefer to be recognized by the pseudonym.
