ah, no fun, I was going to continue the semantic deconstruction with a whole bunch of technicalities about how you're not quite precisely accurate and you gotta go do the right thing and retract your statements.
The first is incorrect, these scrapers are usually distributed across many IPs, in my experience. I usually refer to them as "disturbed, non-identifying crawlers (DNCs)" when I want to be maximally explicit. (The worst I've seen is some crawler/botnet making exactly one request per IP -_-)
I think one could argue that one. Is a DDoS a symptom? In which case the intent is irrelevant. Or is a DDoS an attack/crime? In which case it is. We kind of use it to mean both. But I think it's generally the latter. Wikipedia describes it as a "cyberattack", so actually I think intent is relevant to our (society's) current definition.
The semantics that make sense to me is that "DDoS" describes the symptom/effect irrespective of intent, and "DDoS attack" describes the malicious crime. But the terms are frequently used interchangeably.
