Why do my comments and praises for others disappear on QQ and others' praises don't?

Why you like to disappear:

1, maybe you ordered a little more when you like it. Just click again.

Maybe it's because you have been praised too many times, and you will recover automatically in a few hours.

3, sometimes need to refresh, you have to refresh.

4. It is also possible that someone else has set permissions and you can't click.

5, and Tencent is trying to brush praise, so it will be gone after placing an order.
