A problem with this is you won't know that you have 'lost' these users for several months. It doesn't make sense to take down resources from the site as a knee jerk reaction but it does make sense to focus on other platforms and spend time there adding new content. Likewise with social media links to resources. You don't 'help' or 'support' staff by making their 'terms and conditions' worse. As a company you actively encouraged authors to add lots of resources, with incentives if they did, the forums at the time warned of the problems this would cause. You now cite the very same problems and have changed the system, penalising people who worked hard to produce 100+ quality resources. You obviously know how many will drop from gold to silver next month and have calculated the likely loss in revenue if they stop updating resources against the hoped for increase from new- to bronze. You will have also looked at how active these new authors actually are by monitoring log ins. You will have also estimated the loss in traffic to the TES site in general from those same authors who also use it for news and jobs whilst they check their dashboard. I appreciate this is commercially sensitive but if the target is simply to not lose too many of those dropping next from gold to silver next month you may feel that it was a success but the reality will only become clear over the next 6 months.
