Pre-IPv6 I was always a little apprehensive of using them for general use because it was always a bit murky how they 
collected the IPs in the first place.  This of course excludes email anti-spam reputation services which are inherently 
a different kettle of fish.  For non-email use I tend to favour CAPTCHA (or, hCAPTCHA to be precise, as I don't believe 
in giving Google any more data).

Post-IPv6 I would think IP reputation services are fairly pointless. With people being given anything up to a /48 
without question what are you going to do ? Block whole /48s ?
