What are you current spam filter settings?
GASP Protection, ticked
Default SPAM Action, Move to Trash
Comments Cooldown, 60
Comment Token Expire, 600
Human SPAM Filter, ticked
Comment Filter Items, all selected
Default SPAM Action, Move to Trash
Also, can you confirm your site setting for General > Discusion – “Allow people to post comments on new articles”
I have this box ticked.
More info: I use this on WP Multisite, and I’m having issues on just the one site (though to be fair, it’s the only site on the network that gets any traffic for the most part). I did notice that after updating, the Default SPAM Action settings were different than I’d set them before. They had both reverted to “Mark as Pending Moderation”. It is painful that the settings are not retained after updating. Even after I changed that to “Move to Trash” I have received apparent Human SPAM in my moderation queue that should have gone directly to the Trash.
Before updating, all spam comments were being handled as expected, and being sent directly to the Trash. The SPAM comments in Trash from before the update have “[* WordPress Simple Firewall plugin marked this comment as “trash”. Reason: Failed GASP Bot Filter Test (checkbox) *]” added to them, so I guess those are Bots and not humans?
In any case, still confused as to why I’m suddenly having issues after the updates. Thanks for the help!
