I have a phpLD directory set up on one of my domains, and I installed a script that approves pending links every 24 hours using cron jobs. Recently, I decided to see how many listings were in my directory, and there's around 20k different listings. At fist, I wrote it off as spam, and didn't really care, but when I actually went in to see some of the links, I noticed that most of the links were "featured listings"... How did someone submit almost 20k links directly into the featured listings/categories. Some of the listings don't even have URLs, and that's a required field! I assume that this is a sql hack or something, but I'm not 100% sure. The only reason why I want to figure out how this was done is so I can do the same thing to other phpLD sites. Someone please help me answer this so I can exploit the hell out of it.
