This won't stop someone with enough sophistication.

Not every service will be targeted by sophisticated bots. What kind of service are we talking about? Is it even social? Is it even a service or just a public website?

OP did not provide a threat model or any description of the service really.

Talking about this "in general" is awful and leads to stupid bullshit like endless CloudFlare captchas on literally STATIC blogs.
