I quote the forum rules:
"#Any kind of advertising or spamming is prohibited.
#Any posts that encourage illegal intent will be removed and the account may be disabled. This includes discussion of activities such as music and software piracy and other intellectual property violations.
# You may not post words or URLs that are censored by adding spaces, dots, or substituting characters, or by any other means attempt to defeat any censors put in place by Piano Forum.
# You may not post content, or in any manner link to sites or images, containing pornography, sexually explicit, gross violence, politically or religiously offensive material, or are determined by moderators to be detrimental to the community.
" Take the "Be Polite" rule very seriously! While debating and discussion is fine, we will not tolerate rudeness, insulting posts, personal attacks or purposeless inflammatory posts. Any member who is intentionally unpleasant or disruptive may be banned without warning.
" Political and religious discussions are not allowed in the piano boards." However there is a loophole. "Only postings that are objectively discussing the issue with well backed up facts are allowed."
