There is no definitive answer, as it largely depends on the individual circumstances. However, generally speaking it is possible to write a blog under a pseudonym if the author is comfortable with doing so and believes that doing so will protect their personal information. Additionally, it is important to consider the potential consequences of using a pseudonym when writing. If using a pseudonym results in negative consequences (e.g.
decreased traffic or engagement), then it may not be the best option for the author. Ultimately, it is up to the author to decide whether or not they are comfortable writing under a pseudonym.
