My rep appeared a little strange today morning, to check what was it I went to reputation tab and found:
Who is this user, and why has he been removed?
This, ladies and gentlemen, is why you don't create sock puppet users to upvote yourself, and then try to disguise those sock puppets by having them upvote other users. It might not get noticed right away, but eventually you're probably going to get caught, suspended, and have the sock puppet users deleted. When those users are deleted, it not only affects your own reputation, but it negatively affects the random users who's reputation you inflated.
If we all show respect for our fellow community members and play by the rules, this sort of thing doesn't happen.
Just a reminder: Stack Exchange reputation points are not redeemable for cash, hotel stays, or even airline travel. Reputation is largely intended to give you a sense of how much your contributions are appreciated and have helped people, and to give positive reinforcement for continuing engagement. Upvoting yourself is kind of like telling yourself you're the greatest versus getting a genuine compliment. It's cheating yourself as much as it's cheating the community.
Lastly, I'm sorry to the real people who were affected in this instance. I hope you understand.
"Who" is not relevant, relevant is that the account has been closed/deleted (for whatever reason) and that the up/downvotes given by that account have been deleted.
