Before we get too far into assuming that either the spam filter of a moderator blocked gonwk post, the system may glitch sometimes. I wrote Bubby about this a couple of months ago when I had some posts disappear into thin air. Yet, when I reposted the same message, I got the "It seems you already said that" message. One clue might be whether, when the spam filter clicks in, if it block the message to the poster that "your post is awaiting moderation"? When I had posts not clear the system, I didn't get that message. Maybe that indicated the spam filter got them, thought they weren't of links, for example. Either that or, as we used to say, they got dropped into "the bit bucket". Considering how many messages the system gets, it wouldn't be surprising if there was an occasional glitch. It might be related to the occassional server errors that we get when we can't even connect to GOTD at, or at least certain pages, at all.
So, there may be no plot here, gonwk, just a glitch. My experience is, if you don't get the awaiting moderation message, you can't be sure your comment went through the system properly. What I've done occassionally, is change a word or two, then resubmit. Sometimes it works, sometimes it doesn't seem to go through, either.
Freya, they've had similar problems on the Italian forum. It may be a lack of moderators adept in that language and/or in setting up the filtering for that language.
You only have THREE eyes, Bubby? You must be an outcast among the moderators. What are you, some kind of mutant? :)
