估计没几个读过吧！本来英文就不好，又那么老长，谁会去认真读它呢？所以，虽然购买的时候会出现那些规则，可是我们大多会直接 accept 。
可是，这些规则真的很重要，不认真阅读的话，说不定什么时候它就会让你大吃一惊。
比如 hostgator 主机，禁止在他们的空间上放置下列站点：
unacceptable material on all Shared and Reseller servers include:
IRC Bots, Proxy Scripts / Anonymizers, Pirated Software / Warez, image, filedump, mirror, or banner-ad services (similar to rapidshare, photobucket, or commercial banner ad rotation), affiliate servers, topsites, commercial audio streaming (more than one or two streams), Escrow, High-Yield Interest Programs (HYIP) or related sites, Investment sites (FOREX, egold exchange), sale of any controlled substance without prior proof of appropriate permit(s), AutoSurf sites, Bank Debentures, Bank Debenture Trading Programs, Prime Banks Programs, lottery sites, muds / rpg’s, hate sites, hacker focused sites/archives/programs, or sites promoting illegal activities, IP Scanners, Brute Force Programs, Mail Bombers and Spam Scripts. Forums and or websites that distribute or link to warez content are prohibited.
Using a shared account as a backup/storage device is not permitted, with the exception of one cPanel backup of the same account.
unacceptable material on Dedicated servers include:
Pirated Software / Warez, Escrow, High-Yield Interest Programs (HYIP) or related sites, Investment sites (FOREX, egold exchange), sale of any controlled substance without prior proof of appropriate permit(s), AutoSurf sites, Bank Debentures, Bank Debenture Trading Programs, Prime Banks Programs, lottery sites, hate sites, hacker focused sites/archives/programs, or sites promoting illegal activities, IP Scanners, Brute Force Programs, Mail Bombers and Spam Scripts. Forums and or websites that distribute or link to warez content are prohibited.
还有下面几个，是你极有可能遇到的：
User may not:
a) Use 25% or more of system resources for longer then 90 seconds. There are numerous activities that could cause such problems; these include: CGI scripts, FTP, PHP, HTTP, etc.
b) Run stand-alone, unattended server-side processes at any point in time on the server. This includes any and all daemons, such as IRCD.
c) Run any type of web spider or indexer (including Google Cash / AdSpy) on shared servers.
d) Run any software that interfaces with an IRC (Internet Relay Chat) network.
e) Run any bit torrent application, tracker, or client. You may link to legal torrents off-site, but may not host or store them on our shared servers.
f) Participate in any file-sharing/peer-to-peer activities
g) Run any gaming servers such as counter-strike, half-life, battlefield1942, etc
h) Run cron entries with intervals of less than 15 minutes
INODES
The use of more than 50,000 inodes on any shared account may potentially result in suspension. Accounts found to be exceeding the 50,000 inode limit will automatically be removed from our backup system to avoid overusage. Every file (a webpage, image file, email, etc) on your account uses up 1 inode.
不仔细看一下的话，说不定你就会违反了。不过还好，Hostgator 主机对客户还是比较人性化的，它会发信给你让你改正。有些主机就不一定了，会直接停了你的站。
当年我购买 go-mama-hosting 的主机的时候就吃过一次亏，白白被他们多扣了一个月的使用费。没办法，人家写的清清楚楚，
All outstanding debts (if applicable) must be paid at the time of termination of hosting services. If not done, any future monthly payment subscriptions that may have been setup and paid by you will be applied towards any unpaid balances.
Go-Mama-Hosting is not responsible for cancelling monthly payment subscriptions at the time of hosting cancellation. Any subscription payments received by us after hosting services are cancelled will first be applied to any outstanding balances and the remaining (if applicable) will then be refunded.
CANCELLATIONS MUST BE PROVIDED here 30 DAYS IN ADVANCE OF DISCONTINUATION OF SERVICES.
怪只怪当时我没仔细看！
