Page URL: error in log /catalog7spikes/getfilteredproducts

When webspiders are parsing page with Ajax Filter, they  are causing this error in log file.



This happens quite frequently .I think this is because of code part in rendered HTML : data-getFilteredProductsUrl="/Catalog7Spikes/GetFilteredProducts"

.Can someone explain  me how I can block such things ?
