+## 👩‍⚖️Rule
+
+Service utilization should obey by the rule **"Help promote the service and share knowledge"**. The rule should not be broken.
+
+Thus, it's not ok to hide interactions or responses that can be useful for others to learn from, or and not exclusively, read or search for past interactions.
+
+Although, interaction and their responses can have a lifespan: short, medium or long. A user can delete any of their interactions, which is something the team cannot control. The moderators can also delete them. Thereafter, an interaction type should respect certain lifetimes.
