A spam attack is a spam attack, some of them do more damage like the Ordinals Attack, some do less damage like the spam attack nearly a decade ago with the codename Stress Test; at the end of the day they are all categorized as spam attacks and are all damaging bitcoin.
we have to be careful when we don't even know what the purpose for which a transaction was done and yet we label it as "spam", "unwanted", etc. i was referring specifically to all the thousands of transactions he linked to belonging to that one address. i don't know if they are ordinals or exactly what they are. so i wouldn't want to pass judgement on them yet.
but if you consider it abuse or spam then you know what to do. get segwit changed so that they can't do that kind of thing anymore. but good luck doing that. i don't think the developers care.
At very least, we know transaction which use Ordinal, Rune or similar protocol doesn't have purpose to send Bitcoin to someone else. That alone is enough to make some people classify those TX as spam.
At the end of the day Bitcoin is a payment system not a cloud storage. So whether they use the witness exploit to inject arbitrary data to the chain or OP_RETURN, it can be categorized as abuse and when it is done on a large scale we can call it spam.
Beg your pardon, when was the last time you used BTC and paid something with it?
BTC is slow and expensive.
And what's your point? Some transaction doesn't need very fast confirmation and today's fee (about $1 based on
https://mempool.space/) isn't that expensive if you don't make micro-transaction.
