I turned the comments back on after deeming that the "regular" users of the comments section have cooled down a bit or have become discouraged of it's loss and disappearance. Of course, I was required to delete a few of these comments and block some people. And this is not an easy task to accomplish, for the comments are many and it's hard to judge which one is a problem and needs to be deleted, and with regards to users, it is quite difficult tracking sockpuppets, unless someone is fool enough to post a comment that has information that he/she or should not have known unless he/she is another user.
The comments section is still encompassed by the Forum Policies and FAQ (Upper right), as such whatever comment is posted will be under the judgment of those rules. Now with regards to article comments, specifically Character Articles, if you post a comment on say the Index article, regarding Mikoto or Touma and vice-versa, it will be deleted. Power-level threads, or comments regarding the character's power or abilities in contrast to another is in a gray area, so it shall be allowed as long as the topic remains focused on the character whose artcle you are commenting on.
I used to tolerate shipping comments (just like how I begrudginly tolerate the Relationship Section), but now I will delete them on sight as it will only invite people who do not like that particular ship into it, and no good thing ever comes out of it.
Criticisms regarding a character is still allowed, naturally, but they must "criticisms", a properly constructed comment regarding the faults and weaknesses of a character and what they think could improve them. Outright character bashing like: "This character is annoying," "this character a shit," is not allowed and will be deleted.
In fact, any comment that has nothing to do with the article, for example, talking about a recently blocked user, will be deleted.
Also, I highly encourage everyone that if they see any rule breaking tell them to me or the other mods, since I don't spend most of my time looking at my feed waiting for any rules that have been broken.
May I also remind everyone that if they desire proper and long term discussion regarding a character or any article for that matter, one could always start a discussion about it in the forums. In fact, I encourage such actions.
