We try not to, but if the plugin is a security risk or a resource hog (usually because it’s poorly written), we may have to prohibit it from our servers.
However rare of an occurrence, if this should happen on your site, we will discuss options with you to find an alternate solution. We will never remove or disable a plugin without letting you know first.
We use DirectAdmin. It’s a very powerful, light weight, and FAST, yet easy-to-use control panel that allows you complete control over your hosting space. Check out DirectAdmin.
