the way traffic is counted, and search functions, this incentivizes people to run multiple avatars to camp, which creates fake traffic numbers with zombie alts. Camping is a cancerous activity that destroys community spirit because it engenders welfare state type sense of entitlement, as well as resentment by neighboring landowners for overuse of sim resources. See
http://jira.secondlife.com/browse/MISC-970
for further on this. If we do not ban camping, then changing traffic counting so that all avatars from the same IP are counted as ONE person would greatly reduce the incentive to camp, and would create greater economic incentives for goal-oriented activities like money trees or lucky chairs.
Making noob activities for earning money goal oriented will improve the cultural work ethic in SL, reduce class strife and improve relations between land owners. It will reduce abuse reporting and support ticketing related to camping abuse and noob misbehavior, which will save LL money in support payroll. It will reduce the incidence of sim crashings due to overload and angry residents cleaning out their sims.
The closest you could reasonably get would be one AV per NIC ID (It is unlikely, at least for now, that two legit AVs would be accessing from the same PC - though given hardware to do so, I could set up a Linux system that would allow just that in a few hours: one machine, multiple keyboards/mice/monitors is becoming popular in some educational settings! So even that might not cut it.
One FREE account per IP might work out, and provide and incentive to go premium (so few incentives these days).
