I'm calling this a problem, because it has negative consequences, but many might see this as a feature request.
Please, PLEASE, do an automatic search when adding new topics so see if there are related or duplicate topics that already cover the need. Duplicates dilute the perceived importance of a bug report by splitting the votes across multiple topics, which are not explicitly related to each other. They also cause extra workload for the people trying to respond to the reports.
Also, please, PLEASE, add a feature allowing people to link or relate one bug report to another, so that if a duplicate report already exists, or if someone willfully creates a duplicate (because they want to take credit) then at least people can tie the related reports together after the fact and minimise the damge.
I'm here from the Mojang community where people are reporting bugs on the game Minecraft. The users are predominantly non-technical and therefore don't know about good bug-reporting practices. I found 4 duplicates of one bug in 5 minutes.
