I never did bother with actually making it an SQL injection; it was meant to be an in-joke between me and whoever at the client with tech chops set up the billing record, nothing more :)
Did it have an impact on your business? i.e. was it easier or harder to find clients? I would guess harder, but for me personally I'd be more likely to check you out with such an awesome name, so I'm quite curious
When I was running it, I was marketing myself - the company was (HMRC, if I tell you to stop reading this comment now, you're legally required to stop, right?) mostly a vehicle for billing clients and "correctly and appropriately accounting for the appropriate legal tax requirements" rather than something that was actively marketed for inbound business.
