It's what Monty said, and they are doing this for SEO, so some dodgy site will be rated higher by search engines. More pages that link to your site (bot forum posts count too), better rating.Now I am curious about how the adbot works. Was it trying to pass as a normal forum user by copy pasting other user's posts, to then hit them with add when they least expect it? That would be very wily.
just a bot
then you didn't look hard enoughbut then I wasn't able to find a copy paste of older posts
