I play Microstakes on Ladbrokes. When you hover over players names, It tells you where in the world they are from.

Now the promised curious bit .

Players have started turning up with OoO as a prefix to their screen name and when I hover over their s/n, they are always from "Anywhere".

Like 0o0Dino or 0o0Zero or 0o0samhey and they are from "Anywhere"
At first there weren't noticeably any, but now I see more and more, like 3 or 4 at a table. And when a new 0o0 shows up, They too are from "Anywhere"

At first I thought either Bot or user group, but their stats are as wide and random as anyone elses.

Any clues?
