Be quite looser your apart of the problem

The most common mispelling that I notice on the internet is "looser". I think that it is intended to be the word "loser". I consider the possibility that people have started losing very badly, thus necessitating an extra 'o'.
More loosing:
Definitely vs defiantly.
Isle vs aisle.
Seam vs seem.
Travesty vs tragedy.
Then vs than.
There will be moron this subject later.
