hi;
the rank is teleported if user is full member or above.
trust can not be teleported, we have a classified section overthere so the approach is different.
and i personally do believe that people are naturally good, so it would be unfair to makes the mistakes a user did follow him everywhere.
It's good to believe people are naturally good. But what if they would like to use this feature to scam one of your members. It's unfair for some members who would like to use this feature for advertising their project, but this could be an advantage for scam purposes. Still, if your decision is final, I can't change it. Good luck with your forum.
