So, I've had a craigslist posting bot that's been running for the past year or so without any problems, however, as of recently craigslist has made some changes and any post I make using the bot is automatically ghosted. I've even tried just a single command bot that changes the proxy and then posting manually through the bot window and that didn't work, so somehow craigslist knows that the window I'm using is a bot window. If I just use a regular browser window, IE, Chrome, Firefox, then I can post no problem. Any idea how craigslist knows that it's a bot window?
