There has always been a deliberately vaguely worded rule which has allowed the admin team free reign to ban people if they're behaving like an arse... Even if they are being careful to stay within the rules.
This is done as an acknowledgement that the rules are imperfect, that the letter of the law will never completely accurately reflect the spirit of it, and that people are imperfect too.
Nothing has changed. The only thing the admin team have done, is say they are going to act upon the spirit of the rules (something they should have been doing anyway). That is nothing to be upset by. All it means, is that people will find it harder to be a total arse to other players...
The only reason to be upset, is if you wish to skirt around the rules in order to annoy, upset or anger people, and do not want to be subject to any consequences for this.
