Example: "Watch closely for similar traits including characteristic misspellings of often used words or phrases. Also, shared opinions, education or hobbies could raise the sockpuppet-suspicion. In this case: be aware that some sockpuppets are created with their own "personality" sometimes including a history of their own, as well as maybe some intentional misspellings or different interests from the real person behind the puppet." — wikiHow
There are no particular traits of "a sockpuppet". Sockpuppet masters on the other hand have several things in common.
1) They want not to be recognized as such.
2) They have some agenda they want furthered. Usually selling something or spreading their pet theory. A common purpose in creating a sock puppets is to be the 'straight man' who underscore the points made by the puppet master.
eg:
Puppet master: "And so we see that the current decline of morality will inevitably lead Amerika to rack and ruin."
Sock puppet: "That is soo true. My neighbors son just got arrested for ruining a shopfront with graffiti."
I don't bother with caring. I know who I talk to that I care about and sock puppets are not among the group. I can answer them just fine. An answer is an answer.
Thanks, Pal!
