Spammers register to website manually and post spam contents automatically

Answer 2

I have wrote a blog post Basic anti-spam configuration for Question2Answer:

• change default text strings, which attract manual spamers
• install "Install Very Simple Bot Protection" and create custom anti-spam questions
• deter Semalt using .htaccess.

More details are in post.
