QQ, I didn't send it. But why, there is a saying,

Hello, it should be that you have a dynamic in QQ signature, and QQ signature has been synchronized to QQ space!

I don't want QQ signature to synchronize with QQ space, as shown below:

Open QQ, right-click to find settings and privacy, and then close the "Synchronize personalized signature calls" button!

I hope my answer can help you, and I hope it will be adopted. Thank you!
