Try at your own risk. Maybe if they find it abusive they might block your account. dont do it every week just for important files only.Hey , i noticed this. if you use the above trick, and upload files above 15gb, lets say 20gb. after a few days, dropbox will downgrade it although you wont lose your 20gb(you cant add more thats all). what if i keep doing this method every week and use 100gb+ storage?
