免责声明:这个答案完全与编程无关。但是，它确实试图从一开始就攻击使用脚本的原因。

另一个想法是，如果你的销售数量确实有限，为什么不改变先到先得的方法呢?当然，除非炒作是你营销计划的一部分。

还有很多其他的选择，我相信其他人也能想到一些不同的选择:

an ordering queue (pre-order system) - Some scripts might still end up at the front of the queue, but it's probably faster to just manually enter the info. a raffle system (everyone who tries to order one is entered into the system) - This way the people with the scripts have just the same chances as those without. a rush priority queue - If there is truly a high perceived value, people may be willing to pay more. Implement an ordering queue, but allow people to pay more to be placed higher in the queue. auction (credit goes to David Schmitt for this one, comments are my own) - People can still use scripts to snipe in at the last minute, but not only does it change the pricing structure, people are expecting to be fighting it out with others. You can also do things to restrict the number of bids in a given time period, make people phone in ahead of time for an authorization code, etc.

假定原则:

第一个屏幕必须是非常简单的低开销HTML，带有一个易于识别的按钮(游戏邦注:无论是机器人还是玩家)，以明确表示“我想要我的垃圾”。因为我们假设了最坏的情况-你有来自机器人和非机器人组合的DOS攻击，所有人都首先点击网站(就可识别性而言)。所以让我们尽快把这些从缓存，良性回声机器人等中分发出去。

(注:就追求者而言，这就是发生的事情;这对用户和Woot来说都是痛苦的，所以任何有助于吸收或缓解首次屏幕获取的内容都符合三方的利益。)

然后，对于非机器人来说，这个过程不需要比现在更糟糕，对于正版机器人来说，不需要额外的步骤(或痛苦)。(关于当前设计的背景说明:当前的wooters通常已经签约，或者可以在购买过程中签约。新买家需要在购买时进行注册。所以实际上已经注册和已经登录会更快。)

为了完成垃圾销售，需要导航一系列交易屏幕(比如5个正负，取决于具体情况)。获胜者是第一个完成全部导航的人。当前进程奖励那些最快完成整个5个屏幕序列的机器人(或其他人);但整个进程都偏向于快速响应(即机器人)。

毫无疑问，机器人将在第一个屏幕上占据优势;无论他们在这一点上取得了什么优势，他们都会在剩下的屏幕上保持下去，再加上身体在其他阶段提供的任何优势。

What if Woot were to intentionally decouple the queuing process after the first screen, and feed every session from that point into a sequence of fixed-minimum-time steps? The second screen wouldn't even be presented until 30 seconds had passed; after it was submitted, same for the following screens. I bet wooters would have no problem if they were told that, after the first screen, they would wait in a queue (which is already true) that would spread the load over time in a way that should take no longer than before, be more robust, and help weed out the bots. At this point you can throw in some of the bot speedbumps listed above (subtle variations in DOM objects, etc.) Just the benefit from the perception that Woot is a little more in control of things would help.

If a much higher proportion of the BOC initial hits could segue into a bot-unfriendlier non-time-critical process on their first hit (or close to it), rather than retrying, then real people who get past that point would have more confidence. For sure it would be less hostile than the current situation. It might cut down on the background-noise-ambient-bot-rate that's going on all the time even under normal Woot-Off circumstances. And the bots would lay off the main page and sit in the queue with each other (and everyone else) where they have no advantage.

Hmmm... The concept "apartment-threaded" comes to mind. I wonder if the pattern is approximately useful? A useful core concept here is being able, after the first screen, to track accumulated total time in queue and be able to adjust to standard. As a bot-mitigation strategy, you would have a little bit of flexibility to maybe fudge the very earliest sessions by maybe 5-10 seconds; doing so would probably be undetectable, but would result in a richer non-bot purchase mix. I'm sure you have statistics to help evaluate stuff like this after the fact. Just for fun, you could (at least for one wootoff) put together your own bot that combines the best features you've seen, and then hand it out to everyone the day before. Then at least everyone would be equally armed. (Then duck ... incoming ...)

用户必须等待图像中显示的延迟的延迟页面如何?

你只有在他们在图像中指定的足够短的时间内点击时才会从他们到达的页面进行排序，也许图像可以在动画gif或非常小的javascript或flash计时器中进行倒计时。

如果他们在时间限制之外跳转到详细信息页面，他们会看到在之前的回答中讨论过的昂贵物品。

只是一个旁注:在我看来，问题是，你的用户期望的行为非常类似于一个机器人(大波来，未经认证，点击每个按钮:))，所以验证码可能是唯一能够识别它的图灵测试:))。

让机器人在公平的场地上竞争。加密时间戳并将其粘贴在隐藏表单字段中。当您收到提交文件时，解密它并查看已经过了多长时间。如果它超过了人类打字能力的阈值，则拒绝它。现在机器人和人类只能以同样的速度购买这袋垃圾。

我喜欢BradC的回答(使用Ned Batchelder文章中的建议)，但我想在此基础上再增加一个层次。您不仅可以随机化字段名称，还可以随机化字段位置和使它们不可见的代码。

Now, this last bit is hard part and I don't know exactly how to do it, but someone with more JavaScript and CSS experience might be able to figure it out. Of course, you can't just keep the same positions all the time, because the scripters will just figure out that the element with position (x,y) is the real one. You would have to have some code that changes the positioning of form elements relative to other elements in order to move them off the page, overlay them on each other, etc. Then obfuscate the code that does this with some randomness introduced into it. Automatically change the obfuscation daily, before a new item is made available. The idea is that without a proper CSS and JavaScript implementation (and code to read layout of the page as a human would) a bot won't be able to figure out which elements are being shown to the user. Your server-side code, of course, knows which fields are real and which are fake.

总而言之:

字段名是随机的 字段顺序是随机的 字段隐藏代码很复杂 字段隐藏代码是随机混淆的 服务器端代码每天自动更改随机因子

在你给出的限制条件下，我不认为有办法避免某种形式的“军备竞赛”，但这并不意味着一切都完了。如果你能在军备竞赛中实现自动化，而编剧不能，那么你每次都能获胜。
