这些是什么意思 Prevent users from parking/adding on

freehzw

因为在addon一个域名时，遇到一些问题，后来在WHM->Server Configuration->Tweak Settings中，把这个
Allow Creation of Parked/Addon Domains that resolve to other servers (i.e. domain transfers) [This can be a major security problem. If you must have it enabled, be sure to not allow users to park common internet domains.]打上勾后，终于addon了。 但是对于提到的安全问题有点纳闷: 为什么要 Prevent users from parking/adding on common internet domains. (i.e. hotmail.com, aol.com).   这个会产生什么后果，哪位指点一下，谢谢
