起因是这样的，站长的插件网 http://plugin.blog.fanyongzhuji.com 以前因为漏洞导致VPS被取消过N次，和官方沟通保证甚至发誓了多次的折腾后，不得已将采集功能能关闭，禁用了多个函数，终于没有出现短时间大量流量导致VPS被取消的情况了！但是问题就出来了，因为禁用函数过大，导致无法发布文章，这是次要的。重要的是，我在同一台VPS上放了一个PT小说站，http://book.blog.fanyongzhuji.com ，因为是小偷程序，采集是必须的了。      所以没办法，我就将站长的插件网搬到dreamhost了，没想到问题就来了。搬上去还没到两个小时！官方发来了这样一封邮件： Hello, During a scan of our servers we have identified that your DreamHost account is hosting an insecure website which may be targeted for malicious purposes or has already been compromised.
