Yeah, after Hobbas came a new program called Habbo Guardians, which anyone can become by following the achievement tree which involves voting alongside other Guardians/Helpers on chat snippets which have been reported by other players (Username are censored out, and the player who got reported has their chat highlighted in red text so you can make an informed decision. Helpers/Guardians have the option of voting that the player in question behaved... Good, Badly and Severe, and if majority voted the same then the system would automatically dish out the relevant punishment.
The tool was abused earlier this year and was subsequently disabled for a while, however it is back up and running now.

Now we also have whats called Habbo Ambassadors, which is a programme launched in 2014 to work alongside Habbo staff to assist in Moderating the hotel, ambassadors have 2 key duties, which is to meet and greet players (You'll often find them in public rooms doing this, they'll have the ambassador badge above their head) and also to moderate public rooms, which they have limited powers in; such as the ability to mute and kick players among other things.
