If you watch the mempool/your mempool closely... 2 sats/vbyte prices out the vast majority of spam. And > 2 sats/vbyte 99% of it.

And not only does it get 'outpriced' but it could take days/weeks for the spam to find its way in at .4 sats/vbyte which means it's even more worthless/useless.

If the spammers are going to 'bid up' blockspace... where are they right now?

Influencers some of them are treating this issue unfairly.
