图像托管网站如何执行内容政策？
我正在尝试找出如何最好地实施公共数据托管服务。
允许用户上传图片的网站如何执行有关淫秽图片的服务条款？ 他们是否使用图像处理算法来标记潜在的违规行为（太多肤色像素）？ 我认为 Imageshack 会查看其图片被热链接的网站，并检查关键字。 如果它检测到任何与色情相关的内容，则会删除该图片并禁止该帐户。 还有其他方法吗？
执法很大程度上是自动化的还是更多地基于用户报告？
I'm trying to figure out how to best implement a public data hosting service.
How do websites that let users upload pictures enforce their terms of service regarding obscene pictures? Do they use image processing algorithms to flag potential violations (too many skin-colored pixels)? I think Imageshack looks at the websites that their pictures are hotlinked on, and checks for keywords. If it detects anything porn related, then it removes the picture and bans the account. Are there other methods?
Is enforcement largely automated or is it based more on user reports?

我想这取决于您的“公共数据托管服务”的规模。
如果内容很小，每天可能有几百张图片流入，您可以自行调整它们。
如果有几十万，就需要大量的人来清理杂草。 提交滥用报告的要么是主持人团队，要么是用户本身。
选择哪一种取决于您的服务的预算/财务成功以及服务的类型。 如果是像Rapidshare 这样简单的东西，其中一个人看不到对方在做什么，那么用户看到彼此的内容并通过此通知并希望报告不可接受的内容的机会很小。 如果它是像 Flickr 这样非常社交的东西，你可以打赌，报告将会源源不断地涌入。
我想你可以自动化一些东西，但这几乎是一项不可能完成的任务。 您无法自动检测色情内容。 您无法自动检测侵犯版权的图像 - 对于拥有 Rapidshare、Youtube 等资源的公司来说，制作版权材料的足迹以便将它们与上传的内容进行比较是一个真正的挑战。 目前这种工作只能由人类有效地完成。
它还存在法律问题。 在某些国家/地区，服务所有者不对用户贡献的内容负责（好吧，如果他足够合作，根据要求删除某些内容），而在其他国家/地区，他将因没有预先审核所有传入内容而自行付费。 还要考虑到无论您要在何处推出产品，都要考虑这一点。
I suppose it depends on the scale of your "public data hosting service".
If it's something small with maybe a couple hundreds pictures per day flowing in, you can moderate them on your own.
If it's a couple hundred thousands you'll need an amount of human beings sorting the weeds out. It's either a moderator team or users themselves who submit abuse reports.
Which one to go, can be dependent on your budget/financial success of your service as well as on the type of the service. If it's something simple like Rapidshare where one does not see what the other does, the chances that users will see each others content and through this notice and hopefully report unacceptable content are small. If it's something very social like Flickr you can bet on it reports will be flowing in.
I suppose you could automate something but it's almost an impossible task. You can't automatically detect porn. You can't automatically detect images violating copyrights - making footprints of copyrighting material in order to compare them with the uploaded stuff is a real challenge for companies with resources like Rapidshare, Youtube and others. For now this kind of work can effectively be done only by humans.
There are also legal issues to it. In some countries the service owner is not liable for what users contribute (well, if he's cooperative enough to delete certain content at request), in others he will get the charges himself for not having premoderated all the incoming content. Also think of this with regard to whatever and wherever you are going to launch.
我没有链接，但是虽然这确实是一项容易出错的艰巨任务，但确实存在检测不正确内容的软件。 或者至少 NASA 的安全经理是这么告诉我的 - 如果这只是吓唬我的一种手段，我不知道;-)
I don't have links, but while it's certainly a difficult task prone to errors, software to detect improper content does exist. Or at least that's what the Security Manager at NASA told me - if if was just a means to scare me I don't know ;-)
