When the reason for the report is a generic sentence, it is necessary to read the entire comment thread to understand the full context. Therefore, please write, even if it is just 2 words, why the content you are reporting should be removed. From now on, reports of this type will be ignored (except for some cases).
Also, while we are on the subject of reports and content preferences, I would like to add that this instance does not attempt to appeal to mainstream opinion. Content that does not align with your political preferences may not be removed. However, I am aware that this policy attracts trolls and I try to intervene as much as I can.
If you want a more refined instance, you can try: beehaw.org, lemmy.blahaj.zone, dubvee.org, lemmy.ca, piefed.social etc.
Unfortunately, it's used as a generic message rather than whether it actually violates community guidelines. Frankly, Mlem's approach seems better to me.
I haven't tested it, but it would be pretty bad if reports was also removed from mods when the admin resolved it.
I don't disagree, but mlem's solution is a hacky workaround for the underlying problem. A much more universal and consistent solution would be if Lemmy exposed a list of reasons, which could be edited by community mods and instance admins.
