Last time I mentioned this I probably got ad-words and ad-sense mixed up, but a bunch of people offered to help and send bug reports to the right place.
Here's an image of me trying to send feedback to adwords and it rejecting my real name: http://imgur.com/HdwxGd7
I usually think it's funny when this happens, unless it's a hospital delaying blood test results.
(The feedback was sorted a few days later so they didn't need my report.)
In case you haven't found a way around those ridiculous validations, try adding arbitrary dots ( . ) in the middle of the "offensive" part. Gmail will deliver any dotted version of your own username into your own inbox as normal.
