I don't use Habbo anymore, but:
- megasofer (my sock account that contain/ed all my coins and rares)
- megasofter (idk)
- bunny-boo44371 (now THIS is embarassing)
- GarlicRice
- ForWhat?
- FrodoBaggins!
- Elevenator
- Showder (the one I used since 11')
- Kariann (my actual real name in real life, which I'm surprised that it wasn't used by anyone on Habbo)
