@hehafner,
We are all guilty at one time or another of losing track of a thread.
As much as I like Wordfence (hey, I have purchased licenses) there are lingering issues. As I eluded to earlier there is a performance hit with Wordfence. I first clued in when doing a database backup. The DB had swelled by several megs. Brought the issue to WF's developers attention and was told that the plugin was designed to self-clean periodically; except it wasn't. They suggested installing Wordfence Assistant.
On further investigation I discovered that reason for the mammoth DB increase was the wfHits table. By emptying the table using the plugin WP-DBmanager the DB returned to normal size. Of course this meant that the Live Data was dumped including any IPs blocked by WF, but not the permanently blocked IPs that I had blocked.
If you're savvy enough to venture into the DB take a look at the wf-Hits table and determine for yourself if it is worth periodically emptying. Wordfence Assistant or WP-DBmanager both do the job with less worry.
