More often than not, the best way to hide is to simply blend in with the crowds – this also encompasses one’s choice for a username. It is relatively simple to make a single throwaway account – just come up with a username, and off you go – however, if one makes throwaway accounts often, the task of thinking of a unique, and non-identifiable username can become a challenge. I would argue that poeple would often resort to using a pattern employing small changes for all subsequent usernames. Such patterns can be identified to a specific user if all users have their own unique patterns.
How can one reliably generate many unique-but-normal, and non-pattern-identifiable usernames?
Random nicknames are not recommended, they are unique identifiers, it is better to use nicknames of famous people or movies, video games, etc., because it makes it difficult to find them on the web, especially if different ones are used on each site.
