What's the rationale behind the "no sock puppet" rule?
I have one account on this Board: RPX.
Every time I make a post, the IP address of my computer is recorded (and would rarely vary).
Now let's say I get a very attacking post from Lady Cynthia Fitzmilton.
I now go away and create a new account as Captain Jack Harkness.
Quite suddenly, out of the blue, Captain Jack comes to my rescue against Cynthia.
Captain Jack is a sock-puppet. It's a fake ID standing in for me usually to try and support an unsustainable argument, so I create sock-puppet accounts to generate the illusion that there are people out there who support me.
OSA is very good at this. They will send "sock-puppet" letters to newspapers all over the place to make it look like there's a "grass-roots" movement behind a certain issue when, in fact, the average person couldn't give a damn. This "fake grass roots activism" is known as Astro-turfing
(Wikipedia is your friend.).
Now, if Captain Jack were a real person who lived in my house and joined the forum then it would be wise of us to notify moderators of this because both accounts would have the same IP number attached.
Lastly, Agent Orange is banned from the board. So he creates a new account Billy Botty, and one of his first questions will be, "Why was Agent Orange banned?" trying to get some sympathy.
It basically boils down to the fact that I am no longer allowed to post under the name "Alonzo".
