Similarly, it used to be that you could only register a .org if you were a nonprofit or NGO, but those days have long since passed... I have used .org and .net extensively since 1998 for my hobby sites. When did they force any checks on org? I have never received any warnings or statements suggesting I should only use it for a nonprofit. I have used .org for profit a few times without issue. The .org extension is an open and unrestricted top-level domain meaning anyone can register it for any purpose including commercial activities. At worst using it for anything other than a nonprofit can lead to confusion or trust issues if the site is not obviously for profit.
