Similar screennames that tilt me

[BearHustler]

I cannot figure out why so many people have similar screennames and it's driving me crazy. This is from a 65k hands database of $100NL - $1000NL. I didn't try to find every single screenname with 3 letters followed by 6 numbers, I think you get the point. What's going on here???

the mar make sense as being birthdays with the non american way which is dd/mm/yy like 5/6 of the others are common first names really standard.

So it's a bunch of people born in 1911, 1947, 1922?

Also, if this is really standard, could someone with a decent database of another site check if this is the same at all sites/networks?

Wanted to check if there was a reasonable explanation first.
