Also, on your last note, if a person is being harassed/victimized by another poster -- which has been happening a lot around here lately -- I should think it well within their rights to be the one who complains about it.
I know exactly what you're talking about and I tend to agree, however, I do believe that to be able to complain that you would have to have refrained from responding in kind.
Once you have responded in kind, even though you may have been totally justified in doing so, the issue becomes one of he said/she said. In this case it becomes a matter of justifying your bad behavior by saying the other guy started it.
You need to be careful because to you it might seem that it should be obvious to all that you're the blameless victim but to an uninvolved third party it can get very difficult to assign blame.
This is the point about a situation that requires investigation, where things have progressed over the course of multiple posts in multiple threads. If someone can point to a reply of yours where your response could be considered abusive as well then perhaps this is the case where it's best to make your case via PM to Kryo directly as opposed to using the report function.
As far as the reporting system not making it clear what is expected, I tend to disagree. Pressing the report button brings up the following dialogue. "This form is to be used ONLY for reporting objectional content, etc and is not to be used as a method of communicating with moderators, replying to posts, or for other reasons. Abuse of this form will result in disciplinary action!"
The final sentance seems to be fair warning that reporting is not a trivial matter. Additionally the report function gives you a list of common reasons as to why a post should be reported and SPAM, flaming and trolling are all listed as legitimate reasons to report a post. On the other hand so is a TOS Violation, whatever that may be, so admittedly these offenses are not all that well defined.
Finally, while there are many that would most likely not want to get involved with a flame war that they didn't have to, there are many that recognize who is at fault and have every interest in keeping the peace within our community and would (and have) expressed their opinion to those in charge of who they believe is primarily to blame. But anytime you respond in kind, no matter how justifable your response may be, it makes it much more difficult for those that support your position.
