Specifically blacklisting a group of users because of the technology they use is, by definition, “targeting”, right? I mean, if not, what qualifies as “targeting” for you?
You may be right. I guess it's a matter of semantics. But the way you described it sounded more nefarious. "I'll target this group of VPN users because fuck them, I hope they all die in a tsunami!!!!" when it's more like "ugh, another VPN bot. The 9th this hour and I'm hungry. You know what - I'll just block VPN altogether and go fix me a sandwich." Maybe that's just my perception.
But anyway - it's Joe Blogger's machine, at his home, for him to do whatever he likes. Some rando from the street knocks on the door and says "excuse me, do you mind if I send an e-mail from your computer?" Joe Blogger can perfectly say no, not even an excuse is owed.
You'd have a point if it was a business or a corporation. Some home machine? Out of billions? Why bother?
I guess we're two pedantic folks. I enjoy these discussions. I sometimes gain some new knowledge out of them.
