The moderators are doing what they can with the resources available. They are trying to find fixes to stop the bots.
Captchas were implemented a couple of weeks back..... unfortunately not overly successful ; seems that the bots have some form of human interaction.
Yesterday a plug-in for the cms was added which deals with spam. It needs tweaking. --> you may have noticed yesterday there was a reduction in the spam bots. But, some fell through the cracks. To go along with this some legit posts required moderation (were put in the mod queue.).
The spam bots are highly frustrating. But, it is being worked on.
Tip: instead of making an anti-spam post (ironically there have been many),, you could contact the forum moderators, they are very approachable.
