The edit that you made to the George Washington page was, in my estimation, vandalism. You changed his birth year to something that was clearly wrong. Now if you discovered some new evidence to challenge all previous records of his birth, then you need to cite your source for this. If it was a good faith edit in that sense then I whole heartedly apologize. But, in my judgment, it was nothing more than simple vandalism; and trying to hide any criticism of said vandalism is pointless. The record of all the changes you make are kept indefinitely.
