Please stop doing this. URLs are only dupes if they have had major front page exposure and discussion in about the previous 12 months.

Your comments seem to be bot-generated, and other community member are noticing.

I understand you probably want to help but this is not a positive contribution to HN, so please don't do it, thanks.

how about you pester notorious spammers who do the same but never ever face consequences?

https://news.ycombinator.com/threads?id=ChrisArchitect - the top schizo, one who decided to be the content policeman of this site.

people can't have discussions because mr ChrisArchitect says "dupe". not everyone sits here 24hrs/7days per week and can track all the occurrences of same news topics - not even submissions from same url. what this user does isn't normal and it should look for help in real life.

https://news.ycombinator.com/threads?id=gnabgib - another one, less active but does the same.

We just banned b16m.

Several users have particular aspects of HN they pay a lot of attention to. It doesn't warrant personal attacks or the use of snarky epithets. We often find it helpful when they alert things to us, but we don't always accept the action they advocate. It's no big deal. If you think any of their comments are in breach of the guidelines, you can flag them and if others do the same, their comments may be killed. Or if they're not breaking the guidelines but you disagree with their comment, you can just downvote and/or reply explaning why you think they're wrong.
