Hi, I just discovered this plugin and I really like the idea of it. Kind of like the spamhaus.org idea. Nice.
I've been using WP Better Security and for whatever reason one of the blogs I manage has been getting unusually HAMMERED for days and days, non-stop with brute-force attempts (mostly to 'admin' which there is no user). Setting the plugin to ban the IP after only 2 failed login attempts (sometimes even 1), I've now accumulated a list of IP's to an obviously elaborate BOT-net. (I've got exactly 1938 IP's...and growing...from the past couple weeks.) Each single IP accounts for DOZENS of login attempts, reflected in our endless server access logs for an otherwise low-traffic site.
Wish I would have had your BP plugin installed a couple weeks ago. Adding this data to your database would be highly beneficial for many others and surely put a damper on this activity for all who use your BP plugin.
That being said, is there a way I can contribute this priceless list of IP's to your database to benefit others in the future?
