Please elaborate, why exactly is it antisocial? Because Cloudflare decides who can or cant access a users website? When they specifically signed up for my service.
But how does that work?
Does Cloudflare force firewall rules for those who choose to use it for their websites?
If the tool that does the crawling identifies itself properly, does Cloudflare block it even if users do not tell Cloudflare to block it?
I would argue that the ability to crawl and scrape is core to the original ethos of the internet and all the hoops people jump through to block non-abusive scraping of content is in fact more anti-social than circumventing these mechanisms.
