I’ve been reluctant to post here, as most people are agreeable about changing their titles. But it comes up so frequently.
Basically, the custom user title character limit is obscenely high. When someone accesses the site via Safari (can’t speak to other mobile browsers) it compromises the format of each page the “transgressing” member replied to. So if you scroll diagonally at all (as one most often does), the page goes all over. It doesn’t sound so bad.
