Thanks for the update and progress on the project, I think avoiding abuse is a tough task but at least some effort is going to dealing with the problem... Probably to avoid abuse of multiple accounts, let say, the person upvoting must hold >500 SP, or >1000 SP, this probably would help nullify account creation automation abuse having 1 actor using multiple accounts...It would also give SMT creators some assurance that even those participating has a vested interest but some threshold is needed...
