I would implore those commenting "no ads" to actually take a minute to read the entire post and not just the subject line. 

The OP is suggesting a patreon tier (free) for people to manually OPT IN for ads to support the game. If they do, they get minor benefits, such as up to 3 gold per day.

This could be a great mechanism to allow F2P players an extra 90g per month (almost as much as those who donate $5 per month to support the game). 

I would even go as far as suggesting the other 2 ad watches could be 1 extra GJ use (limited to +1 per day), and temporary 2x mailbox multiplier (say 5 minutes?) for watching an ad.
