There can be no objection to his being reminded, once, that the approach was made. Information for the Guidance of Members of the Craft, 2013, page 36.
Utah: The definition of improper solicitation of a potential candidate is any proposal by a Mason that involves coercion or implied negative retaliation of any kind. 2012 Proceedings Page 39.
Minnesota rule:
Proper solicitation shall consist of the following: A man of sterling qualities may be approached and informed, but only once. He must be left to make his own decision. He should not be badgered
The current understanding in CA is that a mason could tell someone that they think that they would be a good mason. After that, if asked, the mason may provide more information.
