I'm getting a reader complaining that each time he comments, he's getting the following error message/screen:
"Your location has been identified as part of a reported spam network. Comments have been disabled to prevent spam."
I've never seen this personally, but when I Googled (poor Bing) it to try to find out what's going on, the text string seems to pop up for a lot of other websites too in the search result descriptions.
Previously, I've checked my discussion settings (nothing), WP-SpamFree settings (nothing), and disabled Akismet and WP-Spamfree. Only by disabling WP-Spamfree was our commenter able to post. Other commenters don't seem to have a problem, just him for some reason and it seems to be tied to WP-SpamFree though I can't figure out how.
The error message suggests that he's getting blocked because his IP is part of some kind of black list but I wasn't aware that WP-SpamFree uses any centralized black lists (a la Akismet). Again, the user is only blocked and gets that error message when WP-SpamFree is activated.
Has anyone else experienced this? What might be the problem? Cheers.
