hi all, I found several comments comes up, It seems that I have approved them, but I never approved such spam, I wonder if my blog has been hacked? hmmm,any way to find out who approved a comment or the trick the guy employ to make that?
Well, first checked if the wordpress site is set that you have to approve the spam comment before it was implemented. If it was set like that, then one of your moderator or admins or author approved it.
There is no way to check who "approved" a comment, i would recommend you to change your admin password and hosting passwords..
