The below definition of a "sockpuppet" from urban dictionary is very close to how I would describe "sockpuppeting:
A false identity adopted by trolls and other malcontents to support their own postings.
I have not used any alt account to support my own point of view, or my side in a dispute after the self escrow incident. And OgNasty has never lost anyone's money.
Quickseller (your alt) and I were on good terms.
PrimeNumber7 (your alt) disagreed with something I wrote about Quickseller (your alt).
Quickseller (your alt) now agrees with PrimeNumber7 (your alt) not to be on good terms with me.
So I agree that you use your alts interchangeabley to keep both relevant.
