Hi TheDude,
In short.....no!
This is an extremely poor way to build trust. It's manipulative, underhand and will inevitably just end badly.
All it takes is for one person to find this out and before you know it, your brand is tarnished.
In my opinion, how Google views this behaviour is completely irrelevant. Even if they won't penalise you for this, it is still bad business practice. I advise you stay well away from things like this.
Instead, put your efforts into long-term strategies that will help you naturally build consumer trust and with it your consumer base.
The right way is often the harder, but it always pays off in the long term.
Thanks,
