Well the report badges may never come and certainly aren't a priority for theymos right now. People might also be reporting them just to bump up their report count for potential mod positions, but it's rare these days that mods are made on mere high volume of reports. Bump reports are low priority and don't really matter that much, especially when they're buried in old threads but that isn't going to stop people reporting them. I've suggested before that we have maybe two report queues or reports are sorted into priorities as low-priority reports often flood the more serious ones and can quickly bury them. Maybe if we had some sort of drop-down menu where reporters could choose the reason would help and that sorts them by severity/urgency automatically (for instance malware would be high priority and undeleted bumps would be low. High priority could go into a different queue entirely or low priority ones are just pushed to the bottom instead of ordered by the date they come in).
Yeah, they're a minor annoyance, but they are against the rules so people will still report them and quite rightly. I think some users are probably using bots to report them as well. I just wish people would get used to removing them themselves and most will once they're made aware of that but there's obviously a lot of historical cases that can easily rack up your report score.
