Speaking of vandalism and typos, this thread reminds of something I noticed about a year or so ago, I think it was. I was trying to work through some formulas for Keplarian orbits or the precession of the planets or something, and the numbers weren't lining up. I got the distances for the orbits from Wiki, but I noticed that in order for the formulas to work out, the second (or third?) digit for each of the planets would each have to be one value greater (or lower?). So I checked the distances with other sources and sure enough, someone had changed the second digit for the distances of each of the planets very subtly, but effectively for anyone attempting to work with them. At the time, I didn't know it could be edited. I thought it was some prankster hacker or something. I meant to mention it on this board, but I'm not sure if I ever did. I hope it didn't mess with anyone else like it did me; a lot of time wasted with that one. I wonder if it's been corrected, surely by now. I guess maybe I'll take a minute to try to find it again.
