Someone is trying to run through several million ISBNs using a few thousand proxy servers. What is the best way to add Captcha to the search? I'm running v6.5.6 and I know 6.6 has built in Captcha for some pages but not search. I have some customized mods and don't want to upgrade if its not going to help adding Captcha to the search. Thanks! Jonathan Brown

They are just using several thousand proxy servers (non-US) sending ISBNs to the search function. I'm guessing they are trying to get my pricing information. I have a workaround in place for now but need something permanent. Only US customers can send us books through the buyback site so I had looked into blocking all non-US addresses but Captcha on the search seems like a better fit. It's literally a hundred requests a minute at times. Jonathan Brown

I would have thought that if they wanted your pricing they would just scrape the product pages so it's very odd to be using the search for that. Andy Please feel free to review / rate our software

To find out if we are making an offer you have to do a search. I'm assuming the incsearch is where I should be adding the Captcha vs the search page. Any tips or things I should look out for? Thanks.
