The explicit content filter has made using discord rather difficult for me. I get false positives fairly often, and the frustrating part is that I can't do anything about it. Once a message is blocked, it's blocked.
Maybe, instead of deleting the message outright, marking the message as nsfw could work? That would let whoever is supposed to receive it choose whether or not they want to view the image. That way, there's at least an option for it to get through.
Whatever the solution may be, I would definitely like to see see something done, as the filter deleting perfectly sfw images for no apparent reason has reduced discord's usability for me and it's getting quite frustrating.
