How about making what you already have work?? Your "so called" filters have stopped working. I believe it was intentional.
How about something really simple like having filters that actually filter?? Yours suck. They never work. I'm thinking of changing everything over to gmail. If it weren't so time consuming I'd have done it long ago. Making it so your filters no longer work in your yahoo plus so that your customers will have to change to your new service was obviously thought up by a foreigner that is severely ignorant with regard to your customer base. If I'd wanted trickery, all I'd have to do is open some of the spam you've seen fit to let through your faulty "so called filters".
