I still want to implement something to block such nonsense in titles though. But its a low priority.

I hope this does *NOT* get worked on. I believe everyone has the right to write whatever they want in the title, that's why there's a textfield for it. If a certain behavior is required and should be forced on users, it might be better to remove the field and the ability to assign titles to replies, and autogenerate the titles. for individual viewing of notes.

If the context of a certain reply is really that important, it's better to view the root node and judge from there, it would be just one click away. It does not warrant all that work and policies just so that someone can know that the node they are on is a reply to a reply to some reply to a certain node; it gives little information compared to seeing the actual nodes in a threaded display.

The automatic Re: folding is great, because it reduces entropy and removes unwanted data from the title, but enforcing titles is really not the best thing to work on.
