So, I just had an interesting Akismet experience. I posted this reply to someone, and it was reported as “awaiting approval”. I’ve had this happen in the past on similar posts I thought were uncontroversial, and on one I reached out to @orenwolf who told me “Discourse uses Akismet to filter posts for content” and it was an artifact of that.
I deleted the post, and then tried reposting parts of it to see what would and wouldn’t cause it to be held. Finally, deleting the quote from the other user and the clause with the word “troll” in it worked (after which I edited it back in). Obviously, Akismet decided I was being uncollegial to someone else (instead of vice versa), and acted accordingly. This is, as they say in England, “too clever by half”.
(OK, happened again with this post; just the word “troll” was the trigger!)
