Sock puppet

[purpleme12]

I was reading a thread then refreshed it to find it was deleted for having sock puppeting?!
What's this mean?
I don't understand what this means in relation to the thread?

A sock puppet is a second account the poster uses to back up the argument they're making, so they're talking to themselves really. MNHQ can tell by looking at the IP address.

It's a form of trolling basically.

It's really sad.

Although it's really funny when they get the 2 mixed up and expose themselves.

Oh right, strange.
