Rules
Gassho!
Both moderators are Shorinjikempo sensei and therefore bound to a certain degree by the rules of WSKO. But first and foremost on this private(= as in property of a private individual, not as in not publicly readable) forum they're bound by the rules of the forum and of course by the laws applicable, which are determined by the country of residence of the site, as Panu-san pointed out.
More to the point the rules of the forum forbid swearing, advertising, "rudeness, insulting posts, personal attacks or purposeless inflammatory posts". Unless one of these applies I have a hard time seeing why any post would summarily be deleted, without so much as an explanation (as happened yesterday, IIRC).
