Are you kidding? Nobody will take you seriously if you try to pass the 13 y hey off as the 12 y hey. How can anyone trust you when they can't even trust the domain of your email?
I am now the proud owner pv@heyyyyyyyyyyyyyyyyy.com. Looks like I was a bit slow 17ys!
Haha I wonder if basecamp people would get mad and start throwing out cease and desist letters once a bunch of people start using variation of heyyyyyy...yy.com domains for their email addresses.
