People who are "accepted" by the owner of the forum should not be in any way promoted and be able to tag other people's profiles.
What matters now is not how many transactions the account is involved in or how many people left a trust rating but if these people are among the privileged.
If you have a better solution please speak up. As it is the current system is the most stable that we have had. Find a plan for forum trust that can't be exploited, or has a lower risk of being exploited, and I'm sure it will be adopted.
