How to modify a member's status ?

Hello !

I saw spam and link to websites for adults in my board's "Recent status updates" block... The members are not spammers so I wonder if their account had been compromised and how these links have been published in the statuses.

Now, how can I remove these statuses ?

Thank you !

EDIT :

Ok, I've found it : you clik on "See their activity"and then you have "Status updates" on the left.
