Why isn't it possible to make a new ad if the first one was rejected ? I don't fully understand how it played out.
A service about money like this one is a very sensitive business. I'm not sure it's the encryption or privacy the problem. Google has to protect it's ad readers and when in doubt, they probably prefer to avoid it.
As this business is probably starting, it has quasi zero credibility in term of honesty. Other marketing strategies should be used to bootstrap it and grow it's user base. Once it will have a few years without any problem and happy users, it would be more trustable.
