Check about 6000 websites for pornographic material

We have a project to check and verify about 6000 unique websites to see a) if they are active and if so b) if the website does contain pornographic materials. Pornographic materials are photos, images or drawings that relate to sexual activities or sexual explicit information. A photo, image or drawing with at least a naked body part are already considered to be pornographic. A photo, image or drawing that displays a woman in bikini’s or men or women on a dating site ARE considered to be pornographic. The website is considered NOT to be pornographic if a website has only text and/or no explicit images. Please find enclosed the instruction sheet and a sample spreadsheet. In the spreadsheet we already took the opportunity to check the 23 listed websites and logged if they were active and if the website did contain pornographic materials. The list has been sorted on URL. You will find that quite some web addresses are in there more than once. If that is the case please fill in the same results for each URL. Do not leave them blank! The actual spreadsheet has 8300 lines to check, with a bit over 6000 unique URL's to verify. Your output will be the spreadsheet where column C and D are filled out depending on the verification of the website address.
