Block SpamBots - How to

I am sorry if i posted this in the wrong thread.
Just discovered this and i am kinda excited to share it with you guys.

I found a way of successfully block spam bots.

Tried Spamicide and Captcha ,they worked pretty good,but some bots(Somehow) still we're able to pass this security measures.

Recently i found this log in Module :

LoginToboggan

It is not meant to block out spam bots,but its has an option that after users register,they are automatically logged in,and auto assigned to a role(I created a role named "Univerified" which does have only View permission(but not posting one)

After they confirm their email address they are assigned to Authenticated role, but its seems that its glitches our the spam bots,i think after they are auto-redirected and logged in,they detected that there's no email verify need,and they stay online for a while,and then simply leave and never come back.

Since i had this plugin,not even a spam post on my forum has been made.
Some bots bypassed Captcha and Spamicide, so i tought this is a nice thing to share with you guys.

Really sorry again if i posted in the wrong thread (Which i am sure i did)
