(the physical design of your site, the colours, the layout, set the tone for how people behave on it, moreso than you think.)
Anyway we used to mention that in the site rules, the more-people-married-than-banned thing - it's still true, but we took it out because having it there could give people - maybe people trying to work up the nerve to report an abuser - the impression that we don't ban enough people. Or that we want to preserve this ratio by not banning people who need banned.
