Because freedom can't protect itself
"Abraham Cohen's account was deleted from Wikipedia."
His account was not deleted, although it has been inactive for about a month. Not all Wikipedia editors create userpages, the absence of a userpage, such as in this case, only indicates that he never decided to create one, not that any sort of sanctions have been taken against his account.
His account won't be blocked or have any sanctions taken against it since Wikipedia usually warns users for violating its policies, and then only blocks them if such behavior continues. Since his account has become inactive following other users warning him about the conflict of interest policies there is no reason for it to be blocked now.
Just to clarify, his account was not deleted. He became inactive after being warned on his talkpage about editing with a conflict of interest; since he's no longer editing there is no reason to block his account.
You may has mistaken the lack of a userpage for his account as indicating that his account was deleted, but he never actually created a userpage in the first place. New editors and occasionally veteran editors may not have userpages because they never got around to creating one.
