When you create a business which is not yours, until the company which owns that business decides to claim the listing, it's not possible for anybody to contact the business thru Flokii, or to see the e-mail that the creator entered. So, whatsoever the e-mail you enter, it will not change anything.
Personally, when I create a business which is not mine, I enter as e-mail address : email@example.com
if I don't know and can't find the e-mail address of the business I am entering. But even if you enter any other e-mail (true one or false one) only the owner of that company, when he will claim it, will be able to activate the e-mail's contact or e-mail's view for other users
, and in such time he will put the e-mail address of his company, which is the common sense. But once again, the simpliest is to enter firstname.lastname@example.org
.....it's my opinion.
