The Colors! Gallery has a crowd-sourced monitoring system in place to help prevent abusive paintings. In this system, a painting can be flagged as "18+". This means that the painting might be not be suitable for children.
Logged-in users who have opted in to see 18+ paintings on their account page will be still be able to see such paintings, but other users as well as non-logged-in visitors will not.
By default, all new paintings are visible to everyone. New paintings will have "Flag as 18+" button where people can suggest it as a 18+ painting. If enough people press this button, the painting will automatically be flagged as 18+.
Collecting Smiles will normally screen all such content within 48 hours and decide if the painting should have the 18+ flag or not. We use the following guide: "Does this painting contain violence, suggestive themes, crude humor, blood, gambling, and/or strong language?"
