Really? You must know someone from the original gmail team because really short addresses (< 6 chars i believe) were not supported specifically for that reason (anyone who got an exception instantly regretted it). Maybe they relaxed it later on...
I also made spam@gmail.com and basically broke gmail (too many emails to a single destination for the system to handle in those days).. but I got an AWESOME trove of spam reports to use as testing data! =)
On the plus side, I have an account on everything.
