Sock puppeting
Here type an intro instead of this text.

Definition
Put some ideas here too.

When is it good, what is good about it?
And what do you think?

When is it a problem, what is bad about it?
etc...

Should it be allowed, and when?
Go on, keep typing, you can do it!

What can be done to prevent it?
Anything?

What problems might arise if people try to prevent sock-puppeting?
I can think of some, eg it might become hard to submit articles anonymously, Wikinews might start asking for a drivers license to edit articles.

Actions to be taken
None proscribed that I know of.
