Because I'm not able to be around here as much as I used to, I've been using a new plugin to validate new users, control registrations and watch posts for spam. It has been a bit overly enthusiastic in a few cases.
The main things it's supposed to ...
* Check an IP against an IP blacklist and not let folks with those IPs register.
* Check posts for spam.
Now, the plugin's definition of spam is if someone has less than 20 posts and posts a link to an eBay ad or something similar. What it has done is if you're quoting someone with less than 20 posts AND respond with an eBay link, it throws the post in the moderation queue for me to approve or deny. IMO, it's either a bug in the plugin or it's just being overly enthusiastic.
SO, if your thread/post is being sent to the "moderation queue," it is not being deleted. It's just filed away for review. Don't try to repost because that post will ALSO get thrown in the moderation queue and I won't know which post is supposed to be approved.
So, put up with it for a bit. E-mail or PM me if it happens too often, otherwise I'll just check the moderation queue at random during the day.
I'll check to see if I can tweak the plugin's settings a bit, but that won't be until much later today.
