What is the difference between "Invitation required" and "Access only with invitation"?

Does either of these functions limit the number of times a participant may submit photos or vote?

We had a similar discussion here: https://pollunit.com/forum/help-board/difference-between-invitation-required-and-allow-access-only-with-invitation-how-to-input-email-addresses?locale=de

»Invitation required« limits the number of votes per participant.
Limit uploads per invitation is planned but not ready now.

I will close this discussion. Please use the original discussion for further questions.
