Why do the AI bots support the spammers?

Spamming is supposed to be against GAG rules, but time and time again, I see the bots fully endorsing the spammers.

We've all seen it. A user called something like sprocketsRus asks "where can I buy quality sprockets? Then goes on to promote a company called sprocketsRus in broken English.

Immediately the GAG AI bot replies with "sprocketsRUs provide quality sprockets for all your sprocketing needs..."

Surely if GAG is going to insist on AI bots they need to be used to get rid of spammers not support them.

Thoughts?
