My host suspended my account yesterday for apparent massive spamming from my blog.
The following is the notification they sent:
We could see that there is huge spamming associated with your account. This has caused the mail IP to be blacklisted and cause email issues for different user accounts on the server. So, we have suspended your account and null rooted the culprit files. Please take immediate action on this. Please make sure that your account is secured, if you think your account is compromised, then update your password at the earliest. Also see the details of the null rooted files below.
I am the only registered user of my blog and I am unsure of how or what the above files do/allow for someone to spam from my blog. Any help would be appreciated.
