I don’t report a ton of posts, but didn’t you used to be able to explain the reason for the report in a text box in addition to checking a button? E.g., if someone makes a wildly anti-semitic post, currently I can only click a button saying that this is inappropriate, but I would prefer being able to click said button saying it is inappropriate and explain what anti-semitic tropes are included in the post.
There is a “something else” option for reporting a post that has that “text box to describe the something else”.
But I would suggest using the other options (selecting the one that best fits your assessment) and trust that the moderators will review and discuss the issue.
But I do see the flagged post and will take a look at it. IIRC, when we do respond, a DM is sent to you as well. The initial response is usually a generic one to let you know that the moderators have seen it and acted upon it. You can use this DM to add any context or nuance you want considered.
The “something else” box helps, but it’s a workaround if the report clearly fits “inappropriate” and the context matters. An optional comment field on every report category would make it easier for moderators to understand why a post was flagged without changing how people classify it.
