FYI. For a long time my blog was suffering from the spam comments which I would get in my inbox to clear. These were the spam comments which Akismet would not detect as comment and they would show up under a regular Comment queue for moderation. The number of such spam comments were in dozen or so daily and it was frustrating on continuous basis to tend to them.
WordPress suggest that you keep on marking them as spam and they will eventually disappear. None of their suggestion was working as I was continuously marking them spam on daily basis to no avail. Until recently ...
I realized that I was marking them spam from the old comment queue from the Dashboard. WordPress for a while has shifted many of their settings to new and shiny wordpress.com dashboard and there is also a new comment queue. accessible through the top dark grey bar. So few days ago I thought I try marking spam through this drop-down. Lo and behold the spam comment emails slowed down, all magically, from dozen to very few (fingers crossed).
I do not know why WP are keeping two types of dashboard and similar functions at multiple locations. I also do not know why there is no specific guidance on the differences between the two. For example, why is there multiple ways to monitor comments and what is the difference?. I am also technically not sure if what I have discovered above, is true or not. However, sharing this here for others if you have also been suffering through the spam-comment hell.
