Troll? Sock?

Boy, do I feel stupid! But I gotta ask: what is a troll, and what is a sock?

It’s always a good idea to check the database to see if Cecil or his staff have covered a question.
What is a troll?

A “sock puppet”, sometimes called simply a “sock”, is a new account that a poster creates so that s/he will have someone to agree with them and hopefully make their points seem more reasonable.
It’s sad really.

Sorry… didn’t occur to me to search! hanging head in shame

Anyways, thanks 2sense!

By the way, both will result in immediate banning.
