He opted in for one action, and was signed up for two actions. How is the second action considered opt-in?

He clearly did not give his full consent because the UI was designed to bury the thing that he would have explicitly opted-out of.

I think we all agree that he opted in to vouching for the people. The complaint is that it wasn't clear that vouching also entailed sending a message if you didn't opt out of the message portion.

For context:

> FounderDating asked me to identify ten that I would vouch for. I didn’t have to do it but I thought oh well, I guess I’ll do it and see what happens. So all I did was click their photos. Nothing more.

Can't speak to the rest of the flow but clicking photos indeed sounds like opting in.
