How does Lymion protect creators from unwanted photos?

On Lymion, a stranger can't send you a photo. Photo sharing only unlocks once two people are mutually connected, not from the first message.

Inappropriate images are blocked at the platform level, before they reach you. Voice messages are only possible with people you're connected with, and any message, voice included, can be reported.

You can block anyone at any time, and control who's able to reach you in the first place.

This applies regardless of whether the conversation started as a Guaranteed reply or a free message.

Voice messages only exist in free Chat, between people who follow each other, never in a Guaranteed reply, and disappear after 5 days unless the sender keeps them.
