with that said there has been a drop in number of transactions in mempool although the size is still the same so I think they have at least slowed down the spam attack for now.
In current times there is no need for anyone to spam the network. The increased usage and wild price swings make people transact back and forth like crazy, and thus this can be seen as free network cluttering for those who would otherwise spam the network themselves. The only thing we can blame certain miners for, is minting near empty blocks. Today it were BTC.TOP and Antpool who minted both a near empty block, which is just ridiculous in current times. People and services are desperately waiting for confirmations, and these bastards just troll everyone by making them wait longer, and further clutter the network. In the last few days Antpool minted four near empty blocks, which has become a frequent practice for them.
