Rick raised the matter of standards and dignity. Herewith a brief personal comment. We have a number of admins, and they don't all work the same way. But by and large, the super-admin (percy) tries for a comparatively relaxed approach. The two posts you complain about were crude, but not directed against identifiable other posters. Rocket has since been banned for pushing the lines once too often.
Being crass is, well, crass; but not formally in violation of guidelines. If people want to push the envelope they will not doubt find that moderators have wide powers of interpretation, but generally we don't enforce dignity.
