Anti-SHOUT code already exists.

But it works only on comments that are all shouting, rather than some % shouty.

It's the equivalent of:

if comment.ToUpperCase() == comment {
  comment = comment.ToLowerCase()
}

The post in question was typed out with CAPS LOCK on, but the person that typed it still shift-keyed the I at a beginning of a sentence. Thus, defeating the anti-SHOUT.

I can make it work on a % basis, but it could still be defeated by unicode hacks, or quoting some other thing first.

Such things are never perfect... it's more about getting the majority of all shouting comments then it is about making it precise in all cases. The exceptions can be reported (PM me) and I shall deal with them by hand.

Will there be a change to stop SHOUTY POSTS, the brick lane thread first post is all caps.

No need for CAPS to get

shouty

shouty

shouty

shouty

Which could get annoying.
