Well, already knowing if anything like what you described exists it would be great.

Also, maybe an application or instances that would have implemented:

• a system for stricter content moderation, especially something that would automatically delete NSFW/NSFL posts,
• no direct messaging,
• some kind of tool for moderators to efficiently review content,
• multi-layered access to an account to allow for parental control,
• time management tool that would not be based on the client, but with the session duration calculated through interactions.

Thanks for your observation, I will add these ideas to the post description.
