How to change the address of the yellow website and send it to my QQ mailbox?

It may be because the information leaked when you registered other accounts.

Judging from your description, your QQ mailbox will always receive some emails from yellow websites. I think it is possible that some illegal websites are registered in your QQ mailbox, so there will be such spam. It may also be because the information was leaked when registering other legitimate websites. It's best to report here. It doesn't matter if you choose obscenity or garbage. Then don't mess around with information formulas on the Internet.

The above is my answer to your question, I hope it will help you.
