This proposed duplicate is not the same as this question because that is explicitly about SO and the "problem". This question takes a broader approach to the title filter.
This question was inspired by this other question. There's legitimate reason to be upset and think perhaps something has gone wrong, but the deliver of that post leaves much to be desired.
In that post (because I'm sure it will be deleted soon), the OP is complaining that the site (doesn't say which one, though from the user profile I'd go with EL&U) would not accept the following title:
evangelism vs evangelicalism?
However, it did accept the following "improved" title:
evangelism vs evangelicalism? aoeutsnhaoeusnthaoesunthaoesntu
This certainly does not seem right.
So here I am asking if something broke here and if the title checker needs to be improved. Did something fail here? Does it need improvement?
Just to be sure that the OP wasn't exaggerating, I tried this on MSE about 30 seconds ago. Here's the snapshots and a link to the now deleted question.
