Anyone use ZB Block?

[Beluga]

I've set up a forum and will probably install ZB Block to get better protection from spammers:

 

http://www.spambotsecurity.com/

 

I guess it will protect from other nuisances as well, but I'm no security expert. Wonder, if it would help Heliohost in general, if people protected their sites with this?

It uses http://stopforumspam.com/ database, blocking by IP and I'll set it to block IPs a year old at maximum.. Pity it isn't possible to define the age as months, because legitimate IPs can get blocked by accident. phpBB only has a mod that blocks by username/email obtained from the stopforumspam-db.
