使用方法：要屏蔽的用户写到 blacklist 中，逗号分隔。 例如 var blacklist = [286301, 62471, 170185];

用户ID获取方式：鼠标移动到想要屏蔽的用户头像上，点击 Ta的主页 按钮，地址栏中的数字就是他的用户ID

脚本如下

// ==UserScript==
// @name        拦截指定用户帖子和回复
// @namespace   Violentmonkey Scripts
// @match       https://bbs.deepin.org/*
// @grant       none
// @version     1.0
// @author      -
// @description 2023/8/24 15:03:57
// @run-at           document-idle
// ==/UserScript==

var blacklist = [286301];

if (location.href.indexOf("/post/") == -1) {
    var data = JSON.parse(document.getElementById('ng-state').textContent);
    if (data && data.resolver_thread_list && data.resolver_thread_list.ThreadIndex) {
        data.resolver_thread_list.ThreadIndex.forEach(post => {
            if (blacklist.includes(post.user_id)) {
                timer = setInterval(() => {
                    if (document.querySelector('[href="/post/' + post.id + '"]')) {
                        document.querySelector('[href="/post/' + post.id + '"]').parentElement.parentElement.parentElement.parentElement.parentElement.parentElement.remove()
                    } else {
                        clearInterval(timer)
                    }
                }, 1000)
            }
        })
    }
} else {
    var data = JSON.parse(document.getElementById('ng-state').textContent);
    if (data && data['post-detail'] && data['post-detail'].posts && data['post-detail'].posts.data) {
        data['post-detail'].posts.data.forEach(post => {
            if (blacklist.includes(post.post_user_id)) {
                postTimer = setInterval(() => {
                    if (document.getElementById('post_' + post.id)) {

                }, 1000)
            }
        })
    }
}
