The image you provided, was sent within the discord of the Metropolitan Police, with no additional edits.
I recognise that the image can be misinterpreted for something that shouldn't be spread around department discords. I'll see what I can do based on these factors.
There was no reason provided within the ban, however I believe it could be a misinterpretation of NSFW, however you shouldn't of sent this, as you knowingly did.
