Anti-spam plugin blocks spam in comments automatically, invisibly for users and for admins.
- no captcha, because spam is not users' problem
- no moderation queues, because spam is not administrators' problem
- no options, because it is great to forget about spam completely
Plugin is easy to use: just install it and it just works.
What I know now about spam and spam-bots?
- Spam-bots submit all inputs from forms so forms are parsed before being submitted
- If input have 'email' in its name than many spam-bots tries to submit email in it automatically
- All spam-bots does not have Cookies (Cookie array is empty)
- Spam is very complicated now, pretty "smart" and fully automated
