Spam prevention seems to be a bit overzealous here
I have posted a few times recently and have had my posts/comments held back for moderation. On one, I had supplied some text using an old fashioned asterisk divider mechanism. I assumed that was the cause and decided not to use it anymore. But earlier on today, I linked to your API documents in a post and that got held back as well.
I am a little concerned that this is somewhat overzealous and my last experience left me not knowing if the post has actually been sent. I got the notification message (in red) that it had gone to moderators, but the post window was left open and I could have added or edited text and resent it.
