With such thinking, you can generally stoop to the point that let's not report any posts at all.
Slippery slope.
Reporting a post from 2015-2017 may not make sense, reporting a post from 2020 does make sense, as topics containing such posts are often still active, and if they become a little cleaner, no one will get worse from this.
Forum won't become a worse place by deleting 3 years old posts, but I don't think it will become noticeably better either. At least not enough that its worth it to deal with those. After all, I don't think that only important metric is number of deleted posts, but also where and when those posts are written as well, but unfortunately that's info that we don't have access to.
In my opinion, 1 report of a post written today by a signature campaign shitposter is worth more than 100 reports of old bumps and similar shitposts written 3 years ago by some low rank shitposter or paid thread bumper. And that's why I like this new change, because those who like to report can actually focus their energy on something that affects this forum much more.
Yes, indeed, let's put on beautiful badges, and tons of shit will continue to lie on the forum. It turns out that the meaning of reporting is not to remove as much garbage as possible, but to stick some useless nonsense to the user that does not affect anything. Indeed, it makes a lot more sense.
Introducing badges would make people report more recently produced garbage (that's simply how things work as people like these kind of things) which in the end would make this forum much better place than removing posts written years ago. Keep in mind that you are still free to report old posts and they will get deleted unless you report it for one of the trivial reasons.
Is the member who has a reporter badge will be accused and will be hated?
because who knows, the member whose post was deleted, getting not paid because of not enough weekly post quota, and they accused members who have reporter badges
Reports are anonymous, no one except forum staff knows who reported which post.
