Well, it depends from the merit source. From what I understand, some of them are exploring several parts of the forums and distributing smerit to the best posters. Others are mainly local orientated smerit sources, of course they can give smerit to everyone but local posters are their target.
I don't look at the Russian board to judge xandry behaviour very well but if someone is suspecting misconduct of anon xandry, you can pm theymos to inspect his actions.
