Our moderation functions are based on the number of posts that a user has made.
You are likely under that number.
Either that or you have changed your email address or modified your account settings, which also throws an account onto automatic moderation.
We take these steps as spammers have been successfully blocked here at the COW for years and they have gotten more and more aggressive and now make posts under real humanly manned accounts and copy and paste answers, etc., until their accounts are unlocked and then they go nuts across the site.
Because of this, to protect the integirty of the posts across the COW, we have to watch new accounts far more than we used to.
We apologize for the inconvenience.
Creativity is a type of learning process where the teacher and pupil are located in the same individual.
Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away. - Antoine de Saint Exupéry
