The mods know all about BritishMormon. They’re keeping a close eye on him I’m sure. He hasn’t crossed enough lines to get his account nuked, not yet anyway. Though I do think there’s a strong case his modship here has run its course.
The feedback form method is mainly about alerting the mods to brand-new and relatively unknown accounts that are being extremely bigoted, anti-Semitic, violent, etc. BritishMormon isn’t quite at that level even if he is extremely annoying.
