The community and the developers of Bitcoin needs to move fast agains this shit.
We cant give them this freedom to do this so easily.
Maybe we can put a more higher fee if weight more than XXXX but i dont really know how to implement this.
I also think they are exploting the "non censoring" politics of the BTC. they use this in their favour.
So they are giving a bad use not only at the BTC blockchain itself, but also they are making a really shit in community.
Its like BTC blockchain/community give you a opportunity to make something good and you use that to make the worst.
