More spam doesn't help petahash miners to solo mine.
Filters provide greedy miners that put profits above Bitcoin's network health an edge — that's the real attack vector worth everyone's attention.
thanks to mara slipstream- created by anti-knots activist PortlandHodl. Any other examples?
That's a precedent that will only multiply if propagation path remains scarce; meanwhile, junk hype cannot sustain itself by constantly outbidding standard use case. I'm as anti-junk as you but I try to look at things objectively.
If PortlandHodl didn't literally create slipstream, you wouldn't have this argument in favor of less restrictions on spam. Awfully convenient, or are you still intellectualizing?
