I went on it a few times when i was 13 and can truthfully say that I don't remember any explicit material on their until one time when their where some advert banners on there. They didn't contain explicit pictures, but did contain some quite explicit language. Didn't go back there again...

I've used this site on thousands of occasions and have never experienced any problems whatsoever, either with the site or the subsequent downloads. Ads may be a problem for some users but using adblocker plus (Free with mozilla firefox browser) should solve that at source. I've never actively looked for porn on this site but have never 'come across' it accidentally, either (so to speak!). Unless actively searching for porn, you shouldn't encounter any porn here. (And trust me, if your kids want to see porn, they'll find it - and more easily available - in a billion other places online first.) I've sourced some really rare files here in the past (ie old radio comedy programmes) and have found it invaluable - it seems to find content most similar sites miss. I'd advise anti-virus scanning for every file downloaded from the web, regardless of the files' origin, but as I said, everything I've ever had from here has been 100% clean.
