@And now… a Derpibooru user
Duck badges are warnings to other users that someone is an unpleasant person who has a history of creating or escalating drama, but they haven’t been such a problem that we’ve permanently banned them from the site yet. So, hopefully people will take that into account if they get into an argument with “a duck”.
Often, people with ducks have been banned for months or even years before they receive that badge - periodically it gets awarded after someone has been permanently banned for some time, like, a year or so, but is permitted back on the site with some sort of “special rules” for them being here - like, requiring that they filter whatever tags were triggering them so bad they we banned in the first place.
Anyway, normally people are just permanently banned if they are that much trouble or that unpleasant to other users, so duck badges have historically been very rare. In fact, I don’t remember the last time someone was ducked instead of just banning them forever. I think the last person I ducked was someone who had posted a credible threat on an artists life. They’re still on the site today, but they are still in a kind of “double secret probation”, and the duck badge is a reminder for them to not do what got them banned again, and for others to just report them if they see them acting out again.
So if you are intentionally being unpleasant enough to earn a duck badge, you’ll most likely just be banned for longer and longer lengths until you are no longer welcome on the site ever again.
For the 10th anniversary badge,
the info is right here in this thread - good luck!
