@zale023 maybe you can also take a look at this topic from Blindme.
The worst problems, like the one you suffered, came from new users or ALTs that just joined the forum to post scammy links.
So take a look at his topic:
the idea that Blindme posted is to enable people to post links only after certain time or messages posted in forum.
Dan is already working on it.
After you are an old, trusted member of PD and the forum, there should be freedom to post links, of course with the responsability that comes with it....
