I'm not commenting on the value of this project (I wouldn't characterize captchas as DRM, but I see why you have that negative connotation) and I tend to agree with the OP that this is simply wasting energy, but the amount of seething over "anime catgirls" makes me want to write all the docs for my next projects in UwU text and charge for a whimsy-free version.
