Matrix, although I see your point and also agree on most aspects of your argument, some points just aren't logical! Although the rosity team COULD notify all current abusers as you have recommended, it still doesn't put a stop to new user/abusers! Rosity would have to wait for them to abuse before they could be notified to stop said actions, creating an endless and useless process of repeatedly notifying people to stop abusing the system. (Take into account that repeated abusers are probably by nature not very honest ppl, and therefore probably don't care about the wrongness of their actions!)  Also, using such a system allows too many loopholes for the abusers to use to get around the admins! So, rosity would be forced to overwork themselves in and endless endeavor to be overly forgiving! Yes, I admit that it is not fair that the regular (and honest) users of such systems should be punished for what others are doing, but that is how life works...if you allow dishonest ppl a way to be dishonest, they will simply follow their nature! But with this new system, it will EFFECTIVELY stop the abusers! Rosity's other option, of course, would be to put an end to the freestuff section, which I am sure that none of us would want to see happen! Again I will point out that I DO agree with you that it is not fair, I would say to give the new system a try and be glad that the system is still there for us to enjoy, albeit with a few limitations! Just my two cents, hope you take it into consideration!
