A simple suggestion: Allow all internal *.digitalpoint.com/* links in posts since they are references to other posts and no spam. A white list could also be expanded to pictures/links to common reference sites just like alexa.com/*,*.wikipedia.org/*,compete.com/*
You can use the post/thread BBCode to post links to a specific post or thread automatically. You can also use nofollow BBCode to post links anywhere externally. http://forums.digitalpoint.com/misc.php?do=bbcode
oh! i see, easy, thank you ....so its not even to prevent other scam links besides seo links, then only two minor things remain: --since according to your signature all links are nofollow its makes no more sense that its necessary to also add the nofollow bbcode to post them? --when i edit a posting that has already (nofollow) links in it but without adding/changing any links then it will still trigger the alert "Live links and signatures are not available to you yet..." so it challenges you to delete all links and add them once again with nofollow brackets
