1. No AI. Vivarium is a space that thrives on human creativity and connection! We do not allow advertisements for sites that use any generative AI to produce images, writing, designs, promotional materials, or any other content within the site.

2. No inappropriate content. You may advertise for any 3-3-3 forum/writing platform, but advertisements must remain appropriate for a general audience. This includes excessive profanity, discriminatory language, hateful content, or imagery that could be considered offensive. Please denote in your advertisement any note of 3-3-3 content! Thank you!

3. No misleading advertising. Please be sure that your advertisement accurately represents your site, content, utilities, and current activity. Any links provided should be functional and lead directly to the advertised community.

4. No spamming. If you already have an advertisement in our space, please refrain from re-posting. You may re-post an updated ad after 6 months. If you need any help with removing an old advertisement, please contact Vivarium Staff.

5. Respect our community. Vivarium Staff reserves the right to remove advertisements that conflict with Vivarium's values, community guidelines, or general atmosphere.
