parenthetically, i play chess over the internet for socialization and there are some real abusive characters at this internet chess club. But the club has a way of dealing with this problem in their webserver's user interface.
One can type " +cen username" at the command line in the telnet applications chess players use to chat and one will never hear the remarks of angry disturbed racist people.
I mention this to demonstrate that the tools exist for users to modify their experiences in many applications. While I do not know if this is the best policy here-- although I am sure there would be fewer suicidal posts if no one could read them--I do not doubt that there is some feasibility for owl's request if even over the medium term in technical development.
best regards
