Abuse of the reporting system comes under the 'trolling' or as I like to call it, 'asshattery' provision of the rules, and includes:
1) Reporting every post made after one of your posts is moderated regardless of thread, content, tone or the rules and guidelines.
2) Reporting the next five posts by a moderator who has modded you or another forum member who has publicly agreed with said moderation, regardless of thread, content, tone or the rules and guidelines.
3) Reporting broken images.
4) Reporting all or most posts by a particular individual you disagree with regardless of thread, content, tone or the rules and guidelines.
Let me make it quite clear that attempts to intimidate the moderation staff into not moderating you with retaliatory spam-reports will not work.
