WISH: Image Verification for Search after x searches

We’ve had some competitor robots that came onto our site and query our search box 60,000+ times to get our product prices.

We’ve close to 200k products, so each query was putting a huge load, not only that but a sudden drop of orders the next day isn’t funny as well.

If cscart can add a feature that allows store owners to set x times of searches permitted, if > x, image verification needed. it’d realy help us out.
