If you read an inappropriate or insulting message on the forum, profile pages, blogs etc, or in particular, stumble upon spam posts made by bots, please don't reply something funny or angry but report it to the moderators.
Above every post you find that "warning triangle" button, click it and leave mods a message explaining that you think this post is not "suitable".
Mis-interpreting a message can happen but abuse of the report post function will be punished.
