I have added reCAPTCHA to a phpBB forum for user registration and additionally run reCAPTCHA plus a very simple blacklist filter handwritten into the phpBB code on posting attempts from unregistered users, and the spam levels are minimal.
There are a lot of tools to stop spam in and around PhpBB.
Require registration to post
Require email validation to register
Use a CAPTCHA on the registration form
Use Akismet to filter posts coming through (there are a lot of other mods than the one I linked to).
Use moderate-first-post (can't remember if it's built in or an add-on)
But if you're looking for something faster and perhaps a little simpler, PunBB is popular and a fork of it, FluxBB is growing in popularity (since the PunBB brand was bought by "the man").
They are a lot faster and lighter on resources but you do trade in quite a lot of community resources, plugins, and built-in features for that.
I implemented FluxBB in a client's site, as viewable here just to show you that it can be fairly tightly integrated into a site's design. In this case the main site is a Wordpress install.
Just noticed your comment on your opening post. I don't think there are any plug-ins, importers or anything really that will automatically cut down existing spam.
Most spam is very similar. Unless you've been targeted by multiple spammers, you might be able to write a little PHP script to look for known spam signatures and delete them (and their users) automatically.
This should get you back to a point where you can manually moderate quite quickly.

我已将 reCAPTCHA 添加到 phpBB 论坛用于用户注册，并另外运行 reCAPTCHA 以及手写到 phpBB 代码中的非常简单的黑名单过滤器，用于处理来自未注册用户的发帖尝试以及垃圾邮件水平是最低的。

您尝试过 punbb 吗？它具有良好的垃圾邮件和 XSS 防护。
Have you tried punbb? It has good spam and xss protection.
PhpBB 及其周围有很多阻止垃圾邮件的工具。
但是如果您正在寻找更快并且可能更简单的东西，PunBB 很受欢迎，并且是它的一个分支，FluxBB 正在增长受欢迎（因为 PunBB 品牌被“那个男人”买下了）。
它们速度更快，占用的资源也更少，但您确实需要为此付出大量的社区资源、插件和内置功能。
我在客户网站中实现了 FluxBB，在此处可见只是为了向您展示它可以相当紧密地集成到网站的设计中。在本例中，主站点是 WordPress 安装。
刚刚注意到您对开场帖子的评论。我认为没有任何插件、导入程序或任何真正可以自动减少现有垃圾邮件的东西。
大多数垃圾邮件都非常相似。除非您已成为多个垃圾邮件发送者的目标，否则您也许可以编写一些 PHP 脚本来查找已知的垃圾邮件签名并自动删除它们（及其用户）。
这应该会让您回到可以快速手动调节的程度。
