In RuneScape what does locked account mean

It happened to me once. It means if you check your mail on runescape that they sent you if you broke a rule and you press someone else knows my password your accont will be locked. It can mean 2 things. One, u have broken rules in runescape and after 10 black marks and been perm muted your account gets locked that means its perm banned which means your no longer on high scores and you cant get on that account again (they delete your account). The other way your account could be locked is if some one reports the account stolen and then the account gets locked you have to put in all the info you can to recover it. This usually takes 3-4 days to get accepted.
