I have been using Waze for about four years, and, in the last week, I have suddenly been getting "Acceptances" from people that I have not explicitly sent an invite to. As an example, I supposedly sent an invite to a colleague that I am not Facebook friends with, and only recently added them to my phone contacts. At no point have I ever navigated to the My Waze -> Add Friends section, selected them, and then added them. Ditto for a car repair company that I used a few years back - they "accepted" my "friend request".
The only thing I've changed recently is that I added calendar integration.
As I said, I support Waze, and wouldn't even have a problem with this, if I had some option that I could explicitly change to enable or disable this feature.

Anyone else having this issue? Ideas on how to address it?
