Whenever an attempt at a civil, sane discussion is made...
Personally, the vague titles do bother me. But in practice, I don't think regulars should change the titles unless they are straight up misleading or end up being a reoccuring cause for misunderstandings or fights in the thread itself (this has happened before). Slightly bothersome doesn't exactly require moderation in my mind.
Constantly bothersome, disruptive, off topic, intentionally misinterpretative and spammy, however, definitely does.
