Hi Dazzler,
It sounds like a spammer to me, and I'm sure I've seen that id before on the Qwerty part. There's several tricks to running a spammer ID I've learned over the last couple years. Running the IP in google search will often prevail other spam lists from forums that keep a thread that is keeping track of, and also running the id or sometimes the id on the email does not match the log in id, so running that can sometimes prevail. In the ip trace, run the name of the company that is registered through google too! You'll be surprised what crops up for information allowing you to ID a spammer before they can spam your board. And yes, those bots are smart enough to break through registry process's. It just takes them a bit to do so.
In banning a IP of a spammer, sometimes this works, but with bots involved they just use a new id and show up with several ip's that generally are similar just in progressive order, so add to the banning with the host name that shows up in the profile right under the ip when possible, this generally is very effective since it covers the whole and not just one ip number.
I hope you find some of these tricks helpful to you!
