The Discovery Grid maturity ratings are similar to the Second Life and many OpenSim maturity ratings:
Moderate ("Mature" in previous Viewers)
A region designated General is not allowed to advertise or make available content or activity that is sexually explicit, violent, or depicts nudity. Sexually-oriented objects such as "sex beds" or poseballs may not be located or sold in General regions.
General regions are areas where you should feel free to say and do things that you would be comfortable saying and doing in front of your grandmother or a grade school class. Institutions such as universities, conference organizers, and real world businesses may wish to designate their regions as General.
If you are a region owner and you are not certain whether your content and activities are allowed in General regions, it's probably best to designate your region as Moderate.
The Moderate designation accommodates most of the non-adult activities common in throughout OpenSim. Dance clubs, bars, stores and malls, galleries, music venues, beaches, parks, and other spaces for socializing, creating, and learning all support a Moderate designation so long as they do not host publicly promoted adult activities or content and do not use adult search tags. Groups, events and classifieds that relate to this broad range of activities and themes generally should also be designated as Moderate.
Residents in these spaces should therefore expect to see a variety of themes and content. Stores that sell a range of content that includes some "sexy" clothing or objects can generally reside in Moderate rather than Adult regions. Dance clubs that feature "burlesque" acts can also generally reside in Moderate regions as long as they don't promote sexual conduct, for instance through pose balls (whether in "backrooms" or more visible spaces). However if any of these businesses uses adult-oriented search tags, the region may be categorized as Adult and blocked from appearing in non-Adult search.
The Adult designation applies to regions that host, conduct, or display content that is sexually explicit, intensely violent, or depicts illicit drug use. A region must be designated Adult if it hosts, advertises, or publicly promotes:
Representations of intensely violent acts, for example depicting death, torture, dismemberment or other severe bodily harm, whether or not photo-realistic (meaning that images either are or cannot be distinguished from a photograph).
Expressly sexually themed content, spaces or activities, whether or not photo-realistic. We broadly define what is "sexually themed" to include any sexually oriented activities and conduct.
Groups, event listings and classified ads that reference these themes or content must also be designated Adult. We will enforce these rules but cannot monitor all content and conduct within Discovery Grid. Therefore:
- If we chance upon or are told of Regions, groups, and event or classified ad listings that employ search tags plainly suggestive of adult behavior or content require the Adult designation, we will demand you switch your ratings to Adult. We will re-designate such regions if adult content is not removed.
- If we chance upon or are told of severe power-over activities, we will move your region outside of the community area
- Child sexual activity enactments are forbidden. We will demand the activity cease. Failing compliance, you will be banned from the grid and your region deleted.
- As with all reported activity in violation of our policies, we will actively review all reports of adult conduct and provide Residents with a channel for rebuttal.
