First of all, I believe "Sockpuppet" would fall under the category, vandal, as they are just a vandal who has returned to a wiki under a different username. Although your statement is somewhat relevant, as they commit another offense by returning to wiki under a different name to escape blocking. Therefore, this really isn't enough to create a seperate type of vandal.

Also, RRabbit42, you're correct in saying some do not chose usernames that outrigt reveal their true identity. On one wiki I've worked on, we had a user named "BillyCastleman". He was blocked, and he later returned as, "BillyCastlemanPheonix". Another vandal was named RandallWeemes before he was blocked. A year or so later he returned as, "RandallWeemesReborn". I believe that these users may have have purposely made it evident that they are the same person, but, you never know for sure.
