I'm helping out a new client and found that they have #tmp, #prm, etc. in their robots.txt. I asked the web developers if they were dynamically inserting that and what it is. They don't know. I'm assuming whoever was doing the robots.txt before me was putting them in. I'm not sure what they are for though. The web developers think that they are just comments and nothing more. Has anyone else seen something like this? Thanks for any feedback!
