Our spam filter right now is having one of its quirky times, where it mislabels more yummy ham as nasty spam than usual. If your comment disappears entirely* when you hit the “publish” button, then the spaminator has probably sequestered it.
Do not submit the same comment again! This only makes the filter algorithm mark more points against your identifying details, so that subsequent comments of yours are even more likely to be marked as spam.
Try adding a laconic “Mods: I’ve been spaminated.” as your next comment on the thread so that we check the spam filter sooner rather than later and release your comment from the sin bin.
* If you can still see your comment and there’s a message that it awaits moderation, then you’ve probably used one of the words we deliberately filter because of a pattern of past disruption – if your particular usage is non-disruptive then your comment will be approved the next time a moderator logs on.
NB: If you see the ‘awaiting moderation’ message and then your comment later disappears, this means that a moderator has deleted it because it breaches the comments policy in some way. If you’re not sure how it breached the guidelines, ask via email.
