Comments should be relevant to the page that they are on. If you cannot find a relevant page to post on, post at General Discussion.
I doubt if this will be a problem on a fansite such as this (it never has been) but . . . In order for discussions to thrive here, we need to remember to criticize ideas, not people.
So, remember to avoid:
Comments that we find to be hateful, inflammatory, or harassing may be removed. Always strive to add value to every interaction and discussion you participate in.
