Looking at the flags raised by a user, I noticed spam flags for which the account was not destroyed, and for which I didn't see any spam flag raised for us moderators. At first I though another moderator handled the flag, but I find difficult to believe he would not destroy the account.
Sometimes, I notice the IP is marked as blocked, but sometimes it is not. So my question is: What should I do as moderator, in these cases? I understand the absence of flags as telling me "there is nothing for you to do," but is it really so?
To put it in different words, can those accounts do any harm, or are they already blocked from posting on the site I am moderating?
