How do idle fish block some similar information that they don't want to see?

Idle fish encounter something they don't want to see, and directly click the shielding function. When you open the goods you see, a prompt box will appear. There seem to be three items, one of which is that you don't want to see such goods, so you won't see them at all. If you don't want to browse what people don't like sell, you can also blacklist that person directly. After being blacklisted, that person's information will never appear on the recommendation page again.
