This last week almost ALL my trades have sent me bot traffic. I am talking about some of the BIGGEST and most RESPECTED sites on the web. They are getting it from their trades and it is being passed on to their trades. EVEN sites who don't even use trade script is being affected. I just verified with 3 of my trades by matching up ip numbers, that this BOT IS CAPABLE OF GOING UP TO 4 LEVEL deep thru trades. So tracking down the originating site is practically impossible. When you receive the bot traffic from a trade, that trades productivity increased greatly, so this bot is clicking all over your page. The only way to stop it is too look for unusually high productivity, more than 100 repetitive ips outgoing, and block the ip block with htaccess. If you trade at all and think this has not affected you, YOU ARE MISTAKEN.
Here is my htaccess, with many of the ips this bot is using :
