This is a fairly decent plugin, especially for agencies. But, the threat of the MP team blocking my entire account because of client "17" doing some spammy crap is a HUGE deterrent.
Why use this plugin if you've got the option to close my entire account?
I wouldn't.
If you would, please change this to be per website and not for the whole account. At least that would be something that we can deal with. Especially from an agency perspective.
