The amount of spam subscriptions I get with the aweber comment plugin is through the roof. My blog receives about 40,000 uniques a month and 10 new sign ups a day.
Since installing the plugin, I get about 600 spam sign ups. Thank goodness for double opt-in. About 5% of spam actually double opt-in then unsubscribe soon after, most likely just to get my email.
I've deactivated the plugin for now as the few extra subscribers I'd get is not worth the potential spam issues. What can be about this?
