Why can't the niche circle be used?

There are several reasons why the niche circle cannot be used.

1. Group members are full, because Baidu Cloud Group members cannot be added after 50.

2. The group sharer has dissolved the group, so it will not be able to get the group.

3. Another is that the content of the shared group is automatically blocked by the system because it violates the rules.
