Item可以对特定User进行隐藏吗

比如某个Item是由某个User创建的，那么这个Item不想要推荐给这个User。请问能满足这个功能吗？如果可以的话应该怎么配置？

Start by reviewing Gorse's recommendation filtering and configuration documentation to determine whether an item can be excluded for its creator. Define the expected per-user behavior and identify the relevant recommendation entry point and tests before assessing implementation. Done means the behavior is supported or the limitation and configuration are clearly documented.
