My qq space is always posted by people I don't know.

Hello, qq space is often not only about the dynamics with friends. After all, Tencent is a commercial company, and the system will default to the placement of many advertisements, not only in you, but also in the space of many people. This is advertising, which is equivalent to what games or products you pay attention to, and then there will be advertisements in your space, but sometimes you don't pay attention, but some users will post advertisements, and Tencent will distribute these advertisements to some users' spaces. Thank you. I hope you can adopt it.
