You've heard it said that "once you put something out on the internet, it's out there forever." Which is basically a load of crap. Ask the folks at reputation.com!
So you made some comments a few weeks or months or years ago on some blog, and today you are not proud of them, for whatever reason, and you'd like them gone.
You can try finding contact info for the blogh author: poke around and don't forget to mouse over and click on images, as many bloggers hide the keys to contacting them in plain sight.
If you want ME to remove a comment from this humble weblog, no problem! I've done so for several folks already! Just leave me the URL in the comments below (no one will see your inquiry because I will take care of the matter for you and then delete your communication so it will never appear as a "comment") along with your contact info. I will then send you info back so you can pay me the "disposal fee" of US$25.
