Code snippet

This is the optimized code.

The previous code sent messages via web crawlers, Linux control panels, and ad agency detection systems.

I only want to receive notifications for genuine user visits, not from bots, web crawlers, or advertisers.

I’ve tested the code myself; its effectiveness will require further testing over the next few days.

Tips

The previous code was optimized by chatgpt dozens of times, but they still messed with me.

This time, the code provided by grok 4.1 also underwent more than ten revisions.

If it still doesn’t work, I’ll optimize it myself later.
