防止网站和平台存在用户生成的垃圾内容
垃圾内容发布者通常会利用开放评论表单和其他用户生成的内容攻击未设防的网站，在网站上生成垃圾内容。托管平台可能同样面临滥用风险；垃圾内容发布者可能会创建大量不遵循网络垃圾政策的网站，并且生成对网络价值不大或毫无价值的内容。
防止平台或网站上出现滥用行为通常并非易事。简单的障碍（如要求用户在与您的资源互动之前必须完成不寻常的难题）也可能会阻止垃圾内容发布者。
告知用户，不得通过您的服务发布垃圾内容
发布明确的滥用行为防范政策，并将其传达给用户，例如在用户注册过程中显示这些政策。此外，允许受信任的用户在看到您资源上的垃圾内容时进行举报。
找出发布垃圾内容的账号
记录用户平台注册以及与您的平台相关的其他用户互动情况，尝试识别典型的垃圾内容模式，例如：
- 表单填写时间
- 从相同 IP 地址范围发送的请求数
- 在注册过程中使用的用户代理
- 在注册过程中选择的用户名或其他通过表单提交的值
这些信号可帮助您打造用户声望系统，这不仅可以帮助提高用户活跃度，还有助于辨别垃圾内容发布者。许多垃圾评论发布者都希望其内容出现在搜索引擎中，因此，您可以考虑向在您的平台上没有任何声望的新用户发布的帖子添加 noindex robots meta 标记。然后，在用户获得一定声望之后，再允许其内容被编入索引。这会大大降低垃圾内容发布者与您的平台互动的积极性。
由于垃圾内容发布者通常会设法留下指向其网站的链接，因此请考虑为不受信任的内容中的所有链接添加 nofollow 或 ugcrel 属性。
针对可疑的用户互动采用人工审批机制
针对某些用户互动采用人工审批（或审核）机制可以防止垃圾内容发布者立即创建疑似垃圾内容，从而大幅减少平台上的垃圾内容。
审核机制会增加日常工作流的开销，但这是抵御网络垃圾的一种非常有效的方法。鉴于这种机制非常有效，大多数 CMS 内置了评论审查等功能。
使用屏蔽名单防止有人重复发布垃圾内容
只要找到一份垃圾个人资料，再找其他的就轻松多了。例如，如果您发现有多份垃圾个人资料都来自同一个 IP 地址，则可以将该 IP 地址添加到永久屏蔽名单。对于 CMS（例如 WordPress），Akismet 等插件可以提供帮助，将 IP 地址添加到防火墙的拒绝列表有时也是非常有效的方法。
禁止自动创建账号
考虑在注册表单中采用reCAPTCHAs或类似的验证工具，仅允许真人提交表单，从而防止自动化脚本在您的托管服务上生成大量网站。

Hosting platforms may be similarly\nopen to abuse; spammers may create a large number of sites that violate our\n[spam policies](/search/docs/essentials/spam-policies) and add\nlittle or no value to the web.\n\n\nPreventing abuse on your platform or site is usually not hard. Even simple deterrents such as\nan unusual challenge users have to complete before interacting with your property may\ndiscourage spammers.\n\nTell users that you don't allow spam on your service\n----------------------------------------------------\n\n\nPublish a clear abuse policy and communicate it to your users, for example during the sign-up\nprocess. Furthermore, allow trusted users to report content on your property that they\nconsider spammy.\n\nIdentify spammy accounts\n------------------------\n\nKeep a record of signups and other user interactions with your platform, and try to identify\ntypical spam patterns, such as:\n\n- Form completion time\n- Number of requests sent from the same IP address range\n- User agents used during signup\n- User names or other form-submitted values chosen during signup\n\n\nThese signals may help you create a user reputation system, which can not only help you engage\nusers, but it can also help identify spammers. Since many comment spammers want their content\nin search engines, consider adding the\n[`noindex` robots `meta` tag](/search/docs/crawling-indexing/robots/intro) on\nposts that come from new users that don't have any reputation on your platform. Then, after\nsome time, when the user gains reputation, you can allow their content to be indexed. This\nwill greatly demotivate spammers from interacting with your platform.\n\n\nSince oftentimes spammers are motivated by leaving a link to their site, consider adding a\n[`nofollow` or `ugc`](/search/docs/advanced/guidelines/qualify-outbound-links)\n`rel` attribute to all links in untrusted content.\n\nUse manual approval for suspicious user interactions\n----------------------------------------------------\n\n\nManual approval (or moderation) for certain user interactions can decrease spam on your\nplatform considerably by preventing spammers to instantly create content that may be spam.\nModeration adds overhead to your daily workflows, however it's a very effective way of\nfighting spam. Its efficacy is why, for example, comment moderation is a built-in feature in\nmost CMSes.\n\nUse a blocklist to prevent repetitive spamming attempts\n-------------------------------------------------------\n\n\nOnce you find a single spammy profile, make it simple to remove any others. For example, if\nyou see several spammy profiles coming from the same IP address, you can add that IP address\nto a permanent ban list. For CMSes (for example, WordPress), there are plugins like\n[Akismet](https://akismet.com/) that can help, but adding the\nIP address to your firewall's deny list can be very effective also.\n\nBlock automated account creation\n--------------------------------\n\n\nIn your sign-up form, consider using\n[reCAPTCHAs](https://www.google.com/recaptcha/about/) or\n[similar verification tools](https://www.google.com/search?q=alternatives+to+captcha)\nto only allow human submissions and prevent automated scripts from generating a lot of sites\non your hosting service.\n\nMonitor your service for abuse\n------------------------------\n\n- Monitor your property for spam signals such as redirects, large numbers of ad sections, certain spammy keywords, and large sections of encoded JavaScript code. The [`site:`](/search/docs/monitor-debug/search-operators/all-search-site) search operator or [Google Alerts](https://www.google.com/alerts) can help detect problems.\n- Keep an eye on your webserver log files for sudden traffic spikes.\n- Monitor your property for phishing and malware-infected pages. For example, you can use the [Google Safe Browsing API](/safe-browsing) to regularly test URLs from your service.\n- Come up with a few confidence checks. For example, if you're mainly targeting users in Japan, what are the odds of thousands of user interactions from an Italian IP overnight on your property? A number of tools are available to detect the language of newly created sites---for example [language detection libraries](https://www.google.com/search?q=language+detection+library) or the [Google Translate API v2](https://cloud.google.com/translate/docs/getting-started)."]]
