I mean, you could redefine "something that doesn't block all spambots but does hamper a significant proportion of humans" as "successful", but it would be a redefinition.
It's not a definition, it's a judgment.
And whether or not it's a correct judgment depends on how many spambots are blocked, and how many productive individuals are "hampered", among other things.
After all, reverting spam hampers people too.
