There's this weird entitlement people have in which they think that the author of a site is not allowed to choose the method by which they protect their own site because it may be inconvenient to their specific, niche, use case.
Although @Bender's unique answer is better than my obvious observation.
So long as a some half-decent explanation of reasoning is provided.
Plenty of people would say that I shouldn't block residential proxies, but I would 100% block residential proxies if I could.
I think most people responsible for blocking traffic would actively manage their rules if it was costing them something valuable. If they don't notice, then, well no harm no foul.
I gave my explanation, i sometimes have to download something to a server, and this means that I have to download it to my pc first and then scp it, sometimes over an extra server in the middle to get the file to where I want it.
Blocking vpns is the same kind of bad... with governments requiring you to show your ID or do a face scan just to jerk off, vpn usage will go up, and you'll be blocking all those people for no good reason.
Sure, you can block whatever you want, and i can and will hate you for that.
