why do some people become guest, and some become moved on?

[hc8719]

after i looked through some older threads, i noticed sometimes it says "Moved On" under their name. but other times (such as the case of fishypeanut and catfishface) they just become "guest"

i thought it may have been your not on for so long, and you get 'moved on' but that isnt the case for some "ancient passed members"

"Moved On" = banned

"Guest" as their username = self deleted account

"Guest" as their rank (username still intact) = account deleted by admin
