• •Pornography (sexually explicit) or other excessively obscene content (including links to such content) is not tolerated and will be removed at staff discretion. Content including nudity or other graphic content should be clearly denoted by a warning - “Not Safe For Work”, “NSFW”, “Adult Content” or similar. CKA functions with the support of advertisers that do not allow explicit content, so cooperation in this regard is necessary for such content.
