A great number of newcomers have gone nowhere near this web site and never will. Being an open, no password `public` server there is little if any control possible. Its no surprise that the problem visitors rarely if ever persist with bms. They have seen some videos or been told about it. Its free so they take a look with the wrong attitude and no interest in reading more than they need to. The ip is well spread by word of mouth and mentions on the web so its open house. SOP`s are for the people who follow rules. There is some appropriate information here that might be added to but ultimately likely will not deal with what you experienced.
