On three of my WordPress blogs (version 2.1.2) a spammer has erased my posts and replaced with spam that is set to "no display" with CSS.
I have backups generated by Austin Matzko's 'WordPress Database Backup' plugin, but I don't know how to use them. I tried to "import" and it didn't work.
How can I prevent this from happening again? How can I restore my posts? I have set all the missing posts to "draft".
I'm sure others are having this problem; I couldn't be the only one. Any insight on how a spammer can delete my posts and replace with spam?
