Recently, the dupe command has received an update that made it accept multiple suggestions at once, and then merge them all into a single one
Is your feature request related to a problem you're having? Please describe.
I'm always frustrated when I find some old dupe on the site, or another custodian beat me to the punch for any of the suggestions I want to dupe. If any suggestion is marked as answered or already duped, the bot will just give a vague message that tells me that, so I have to scan every suggestion I put in to remove the unacceptable ones.
Describe the solution you'd like
Filter out answered and already duped suggestions from the command, and if nothing can be dupe, throw an error.
