Hi @wpb regarding you comment
I’m also looking at it from the perspective that Dfinity so far has not provided much input on all the forum topics that have been submitted to address spam proposals
It was important to us to not only answer to each of the solutions but to also propose a more systematic way how different solutions can be assessed and compared. We have now published our proposal here. As mentioned we would also like to participate in the different discussions. I will lead this effort from our side. As so many discussions happen in parallel it might of course be that we missed something. Please feel free to flag individual interesting ideas to us (best to directly tag me) in case we missed any!
