Fmucker

Seriously? It's not the fact that someone would actually choose this for a screen name it's the fact that PokerStars crack IT staff would allow it. The correct response to registering with this screen name is that there would be a polite message from Pokerstars that would read something like this:

Dear fmucker:

I understand that you want t pick a pungent screen name that identifies yourself as an individual and separates you from the pervasive AI and the two year olds that play here. But alas as there are two year olds here we must insist you pick another name as the current choice is too close to mfucker which is something we simply can't allow. As a magnanimous gesture we will allow you to purchase 1 billion free money chips at the bargain price of $99.99 US Dollars. Please ignore the fact that the currency is US Dollars when US players are not allowed to compete for real money. Trust us that our next upgrade will be to change the currency to Euros and Bitcoins.

Have a nice day mother fucker.

PokerStars.
