Assuming the behaviour was repetitive and unwarranted, isn't your above example more a case of spam classification?
What you're proposing in this poll is, if Mikey doesn't like Chance, and Chance posts on Mikey's journal, Mikey can ask that Chance's post be removed for violating no rule whatsoever, and you would be obligated to remove it. In this case, why not make it so that the OP is the only one who can post to his or her own topic—instead of giving each OP the ability to define what the rules are for their own topics?
People won't always agree, and some posts may offend some. Does this mean that the OP should be able to dictate rules as to what they find personally objectionable? Wouldn't they be better starting their own website or forum, where no one can post but them?
Being part of a community like this means interacting with people who don't always share your point of view—and giving everyone the ability to censor other community members on an arbitrary basis with no rational basis for review, especially when there are kids on this forum, is like allowing a child to make up his or her own rules, so long as they stay in their room.
