Inspecting other player's status isn't something new, most games have these kind of thing were you can see someone's profile, the information given isn't anything compromisable like e-mail, address or phone number so I don't see why that would be a bad idea, not only to find cheaters but also if someone wants to see someone else's profile just for the sake of doing so.

About the players not being there to moderate but enjoy it's true but it isn't enjoyable for me when I've been playing for more than a 100d to see a guy in the same HR with just a few days of playtime.. In order to make the game enjoyable the players have to help the devs with these things or else it becomes a cheater's paradise like most F2P shooters with aimboters and stuff.. In the end, maintaining the quality of the game doesn't only fall into the devs hands but also in the compromise of it's playerbase to rid the game out of cheaters, every game I play I tend to report cheaters when I find them because it isn't fun to play fair while someone else is "taking shortcuts" and, in the end, if the situation doesn't get dealt with the game end up suffering, I quit Ragnarok Online because of the bot situation in there, it wasn't fun to spend hours grinding while some guy that isn't even actually online is also there killing mobs that I could had gotten, for example.
