It is both an idea and a kvetch...
My hosting account was now just restricted and access to all my WP sites is blocked.
The hosting company is saying it is *probably* because of a WP plugin, but they don't have any tools or way to tell me exactly what is wrong, so I cannot disable/delete the offending script/plugin!
As WP is the "hosting" application for the plugins, it must have a way to control its "guest" plugins - monitor, log, alert (email) and restrict and/or block misbehaving plugins, on CPU load and memory load (and possibly file system usage, but it is less of an issue these days).
It is not logical that we will reach a state when one plugin is taking down a complete hosting account.
Adding content features is nice but there should be better foundations.
