A few days ago a member told me his wife signed up to UKP, when I checked her account it showed she was constantly trying to view his profile's post history and review history but was getting permission denied notice.
Might not save him from a bollocking from his wife or divorce, but it might help in a small way.
For this reason, and others (e.g. pimps stalking punters here), I have no intention on return to what the site was before where anyone, even with zero posts, could do what someone with 500 posts could do.
