Yeah. I just wonder what the sweet spot is for enough POW to deter spammers, but not too much to prohibit mobile keygen. If the spammer is using cloud infrastructure, then this may not be possible

I see sats as derivate of bitcoins PoW. Making PoW work once was hard enough.
Not everybody has sats readily available; shouldn’t be a requirement to start using a new protocol/product you don’t know to jump through so many hoops
I think I’d you mix POW with WoT you can get a sweet spot that is not costly; spammer and new user start from zero reputation but they should quickly differentiate themselves and the required POW can decrease as their WoT increases
