SIMPLEST ANTI-SPAM EVER: Couple of lines of javascript to check for key clicks making sure it's a human typing during registration or during blog posts makes tools like xrumer completely useless.

Yes, I force javascript on my users to stop spam, and
No, it hasn't hurt my site performance or caused member outrage whatsoever.

If it did cause member outrage, I'd probably tell them to go read the spam elsewhere.

I also require email validation on all accounts and those that don't validate their email accounts are automatically purged in 5 days.

There will be a bunch of backlash here about the practice of requiring javascript, but I don't care (aka save your breath), it stops spam cold, and in actual practice most have javascript enabled anyway.

A few years back I was overrun with spammers and spamming attempts until I implemented this.

Today I have none, zero, nada.

They simply gave up, no trace of spam attempts in the log files, nothing.
