Recently, in Taiwan, using the iPhone app "Line", their advertisement includes daily conversation. Their ugly truth is that "Fruit ID" in iPhone listening everything 24 hrs, recognizes keywords, gives them to Line (also other businesses like yt), then matches them, and sends the advertisement to the Line user (link with the same "Fruit ID"). Many daily work groups use the "Line app" in real life, so I using it.

I tried the "Letmebe app." The function includes blocking the "Line app" or adding IP. I want to block only advertisement IPs. I guess a VPN can design this function. Here is what this function may look like (in my imagination):
1) Open the Proton VPN app.
2) Users click the "block app ip" button, then choose "Line app."
3) Click "scan and show me all active IPs in the Line app."
4) Click and block IP, and open the Line app to see if the advertisement fails to load.
After several tries, the user can get the answer -- what IP is advertisement IP.
5) Block the advertisement ip. End the wrong loops of the human world.

I appreciate so much effort the Proton staff put into it. 🙏
