Hi, I'm running a community website. I recently found there's an obvious increase on the percentage of porn images uploaded and also had a couple of complaints from some of my users. I don't have much time checking each and every picture uploaded, so I googled a bit and found some software http : // pikture . logikit . net or http : // www . ltutech . com /en / technology-and-products . image-filter. html or another filtering program? pls tell me Thanks.
