@lovesmayfamilis, how do you think he hid his last forum visit date? We used to be able to see exactly when someone was online, but not so long ago, a user's profile shows "Recently" if the user hasn't been online for more than 72 hours -> Small improvement regarding activity / "Show others your online status"

Now it is more than evident that all three profiles are connected, the only question is whether another one will appear in the future.
