Ohh. You meant the creation of the attic to catch ABers in the attic?
It would be kind of hard to differentiate ABers (who use reasonable settings) from the legit RSers though since legit RSers would also be refreshing continuously quickly.
Plus, people who use ridiculous AB settings that are more obvious would probably not have 3 yr + accounts for long.
I think the better way of thinking is that TNT is trying to lower inflated items... if they are trying to freeze people in this then say byebye to all the old accounts on neopets.
