Eugeniu Croitoru, the Moldovan man who set up the Facebook page, told the BBC:
The idea is very simple. 'Bill' can be anyone who is smart and has common sense and doesn't do annoying things. You'll also notice Bill can be someone who makes fun of himself and jokes about others too occasionally.
Debabrata Nath, a friend of Croitoru who helps to run the page, explained to BuzzFeed:
Most people tend to take it in the way it should: as a joke and something which is meant to be funny and not taken seriously.
But clearly not everyone is convinced
There's now a counter page called "Don't be like Bill"
