Can A Hack Occur Via A Product Listing?

I am losing count now but I have checked over 20 and they are all from [color=#000000][font=Helvetica, Arial, sans-serif]Chinanet Fujian Province Network[/font][/color]

[color=#000000][font=Helvetica, Arial, sans-serif]visiting the same product and only showing up in cpanel but not Admin’s Statistics. [/font][/color][color=#000000][font=Helvetica, Arial, sans-serif]My host says I am being ‘crawled’ and that it’s a result of running on an older version of php 5.3 Bunch of pr@#ks. Why don’t they just crawl back under their rock.[/font][/color]
