I personally, am grateful for those who mention such things as animal abuse in the title as a warning. I will not read such a thread, given any choice, so for me, it avoids something that can be very upsetting. On a forum dedicated to politeness, I do think it's a courteous thing to do. So "thank you" to those who either use descriptive titles, or add warnings on subjects that may be upsetting to other posters. It's also a nice touch if "sensitive" parts of posts are whited out for the benefit of others who may find such information confronting.
