Community Quiz - Pick player type

I got the following SMS from an unknown number "Turned $100 into $3475 last night @ conrads. $2.50 - $5 no limit :-) 5 hours".

I set about trying to think who might have sent it. I have met quite a few people through poker. Conrads is a Casino on the Gold Coast in Australia which is a vacation destination.

My immediate candidates were a rich aggressive ex-semi-pro who played in the WSOP 15 years ago, an FX Trader who bluffs a lot and is loaded so doesn't give a sh**, a solid female who plays marginal hands fast and gets action because she's a female ... and then I ran out of likely candidates.

This is an incredible result. It was a 40BB $200 max buy-in table so that is 15+ BIs. I can't recall ever seeing a stack like this online. I'll be interested in guesses on playing style. Answer to follow when the regulars have had a guess.
