About the relationship between donation and trust, I'd generally say, it gives you a base; By that I mean, I'd generally say a donator can be trusted with the 50% value of their donation at the very least, mainly because if they were to scam, they'd make a loss on it technically.
For the SVU, do what Superman told you, it's your best shot.
Also, I suggest you check vouches always and check for quality as well [if you want to determine how reliable a user is].
