Both title and body can be artificially extended by appending <div></div>. Character entropy is still enforced properly though, after the markup has been removed from title.
This might be seens as a power user feature and frankly I quite like it, but it seems like a bug nevertheless.
Proof of concept (following post):
Personally, I wouldn’t bother fixing this until some kind of incident happens - someone using it to be obnoxious. The fix might be pretty involved, and it has questionable benefit – what are we really trying to discourage here? The wrong thing is already hard - you have to consciously put the effort into submitting a post that’s under the character count.
Also – I’m using – too many dashes.
Right, right, that pretty much articulates what I thought. I’m happy this „feature“ is to stay for the time being, but I thought I would bring this up in case somebody deems it terribly insecure.
This “bug” has been open on Stack Overflow forever, too. Not a bug, that’s just the way it works. Always some way to get around it.
The real solution is that people who keep doing this get banned
