When creating an alternative name for a sock puppet account, sock puppets normally create random users names or will often stick to derivates of their original name such as using different words that express the same concept or simply add new digits like numbers and letters to their names if they wish to be discovered. These derivates are familiar to them because they may have a connection with them being their preferences, self-being among others. In the case of harassment and causing drama and trouble, sock puppets may choose to bear almost the equal user name with just some small modifications, a trait I have observed in many sock puppet accounts. However if a sock is designed to actually help and support their puppet master they will likely choose a different user name that doesn´t have any sort of connection to their other original account.

Depending on your online activity, it can get quite cumbersome to delete all your online traces. Do keep in mind that it is almost impossible to completely delete yourself from the internet if you have spent enough time on it. There is a chance your data might be lurking on the dark web, someone might have stolen your data before you could delete it, or simply its stored on a company server and that choose not to delete it. However, in most cases, you are sure to delete most of the publicly available information about you with the use of some tools available on the internet.
