Amazingly simple and affective

This plugin works great on wordpress sites. I have a dedicated server with 70+ websites that started sending out SPAM – I looked for a solution and found this plugin. I had all my hosting clients install and run it. I would love to have been able to just use one login (mine) and donate a larger sum so I could put it on all my sites. It seems to be thorough and has stopped my server from being shut down. Thanks for all you do1
