Accounts hacked to flood and post bullshit

Hello
I'm suspecting someone has hacked some old user accounts (created 4 or 5 years ago) to flood and post bullshit the same day (8 January):
Liger14 memberlist.php?mode=viewprofile&u=12308
trinity memberlist.php?mode=viewprofile&u=642
(both ones have been banned)
Some users reported some of these posts, that's why I saw that.
I'm not admin so I can't check if the password of these accounts has been recently changed or something like that, anyway you're aware of that now.
