Well, if that indeed were true ("...size of the posts database."), then the same would be true for any query such as the one I mentioned in my opening post. Since I noticed that if I click on your name, I am presented with a page offering a link to display, through a script, all the posts you have made or all the posts you started. How much trouble do you believe it would cause to make a script to display all the posts made on a certain date? Searching for a user's posts seems to work without running a risk of a denial of service. I guess the idea behind how it could be a DoS went over my head.
