账号管理脚本，可应对长名刷屏

非常感谢！我学习学习，然后再来汇报一下试验结果。

如果冲突了，还是以猫狗的脚本为主。 因为如果ABP删除了DOM节点，那么暴力猴插件还是读不到长文本ID的length属性的。

使用Adblock Plus 插件，可以屏蔽首页、二级页面、文章页的长ID的DOM节点，但是尚不知是否和暴力猴插件互相冲突。有兴趣的话可以尝试tor中下载。然后点击右上ABP图标，点击齿轮图标，进入设置页面，点选"高级"选项卡，“您的自定义过滤”->"我的过滤列表", 添加以下文本，可以有效解决浏览器卡爆的问题。

2049bbs.xyz##.item-date

        var toolong = uname.length> 16
        var shorter = n=>n.slice(0,16)

改成

        var toolong = uname.length> 32
        var shorter = n=>md5(n)

因爲前16個字節一樣，你slice就重複了。。。

然後就會rename失敗

突然好感动：小二要是知道猫猫以及大家为维护这个网站花了这么多心思一定会很开心！

效果：

可以将长名字改为md5的新code（在改了的名字前加md5“标签”）：

@霏艺Faye #4 转换成md5 hash，真是个聪明的好方法！谢谢霏艺~ 我去试验下玩玩。

@natasha #5 唉，也不知道他现在怎么样了。

@阿離 #3 谢谢阿離妹妹啊~

补充，“限制”的选项是我后来加的。需要在link.style='color:green'之后，elem.appendChild(link)前，加上一段：

    elem.appendChild(link)

    link = dce('a')
    link.innerText='限制(6)'
    link.title=`按下后“${uname}(${id})”不顶帖，帖子折叠`
    link.onclick = function(){form_flag_post(`/admin/user/edit/${id}`, {act:"flag",flag:6})}
    link.style='color:purple'

@霏艺Faye #4 试了一下，出现了"ReferenceError: md5 is not defined"。我的Tor version 是9.5.1 (based on Mozilla Firefox 68.10.0esr) (64-bit)
