On the "A Day In The Penalty Box" post's comment section, someone posted,
If your account has been suspended, do you lose the opportunity of becoming a moderator? My brother has an Arqade account, and so do I, and I was suspended for having a sockpuppet, when in reality, it was my brother’s account. Now, his account has been removed, and he is very upset.
In the post, the user meant that both his brother and him had Arqade Stack Exchange accounts and that he was wrongly accused and suspended for having sockpuppets. However, can his brother's account (or anyone's in a similar situation) be recovered with all the previous reputation and badges? And also what should someone do when someone is wrongly accused of having sockpuppets (e.g. someone serial upvoting you and/or posting questions and answers like in the way how you do just so you can get suspended)?
Specifically, how can someone credibly prove to a site's moderators that two accounts belong to two people from the same location, rather than just one user with sockpuppets?
