I don't know about you, but I've had it up to here (gesturing towards my chin) with new users who are only out to abuse the system.
I would like to see a threshold of contacts or companies added BEFORE a user is permitted to edit or graveyard another users' contacts. I'm thinking a combination of at least 100 adds be mandatory BEFORE editing permissions are granted. Yes this would mean a major "raising of the bar" but in this case I feel that it would permit, only users with the most serious of intent towards making positive contributions, entrance to the system. This measure would prevent new users from accessing the referral system until their credentials are proven and a significant, legitimate contribution to the data has been made.
I feel that this would go a long way to preventing the abusers who open up a new account just to see how soon and how much they can get away with before they get caught.
In addition much like the stolen merchandise lockup at a police station, I would like to see that once an abuser has been locked out by Jigsaw permanently, that the "stolen merchandise', ie the contacts, be returned to their rightful owner prior to the crime, regardless of what has happened with the contact since the initial incident. Further, any legitimate contacts owned by permanently locked out users, be redistributed to community members in good standing, who have made at least one positive contribution during that monthly period.
Contact protection coupled with crime prevention. Who can argue with that?
