I thought I should clarify a few things about internet search engines. There are literally thousands of search engines and web-crawling indexing programs, not just the big ones everyone is familiar with (Google, Yahoo, MSN, etc). Everything that has ever been typed on this website and listed as "public" even for as little as a few hours is probably stored and indexed somewhere on the internet, never to be completely erased. The search engines not only record the webpage addresses, but they actually keep cached versions of each page also. If you play around on Google and some of the others, you'll find that you can look at the way websites appeared years ago, before any site updates, etc. This is done because the search engines have cached images of those pages, even though they may not have even existed for years on their original servers / sites. Changing a post to "private" or even deleting it only gets rid of that instance on the DietDiaries.com website server, those pages still exist plenty of other places. This is typical of pretty much any internet site you have ever typed anything on. There is no completely anonymous way to post something that other "humans" can see, but not have it "seen" by the search engines also. If you're concerned with someone tracking you down on the internet, the only "safe" way to combat that is to not use the internet.
