Why does Mobile Fetion send text messages directly without adding friends?

Fetion is to add the other person as a friend first, and then send him a text message. "

This is to prevent malicious SMS harassment.

If you use a mobile phone client, the other party is also a Fetion user. You can send it as long as you add it, without the consent of the other party.

This is just personal experience, Fetion is not unlimited. I have tested that the number of articles per day is limited.
