Sorry, basically the spam system is a bit aggro on some things. It doesn’t seem to like things that just consist of links. Unfortunately I can’t approve stuff, it just gets tagged and rejected. Over time, the more non-spam (in its opinion) that you post, the more you are able to post but if you start out of the gate with just a link it doesn’t like that.
Sorry for the hassle but the spam problem has gotten completely out of control and an automated system to manage it is necessary.
I am going to push for a way to whitelist people manually but that doesn’t exist right now. In the meantime, sorry for the hassle.
