Article comments can be deleted yes. But I'm pretty sure it'd become troublesome to delete all the article comments that aren't used as the site wants them to be used as. For example, people commenting on a character rather than how to improve the character's article itself. It'd take most of an admin's time just to delete all of those.

Not to mention, my Bleach and Naruto fanon wikis have come under attack by raiders like 4chan's /b/ board, and when they come, they bring hordes of anons with them; the damage of which can take days to reverse. Article comments are just invitations for these types of trolls to spam until their heart is content.

Message Wall will be the same, I guarantee you. There is no reason it shouldn't be optional. Talk pages and Message Wall are two features that have fundamental differences in the way they work. On some wikis, Talk pages are better for use, while on others Message Wall may be better. It should be optional for this reason; a feature that can be turned on and off with that wiki's community's approval. Not a Wikia wide decision by the staff.
