MediaWiki:Abusefilter-linkspam
Due to heavy spamming, new and unregistered users are prohibited from posting links.
I apologize for this inconvenience, however, due to rampant abuse of this site, and very few legitimate edits involving external links, I've disallowed posting of links for accounts less than two days old.
If you have a legitimate reason for adding a link, swap the first t's with x - like hxxps://example.com/ - and one of our users can review and update it to a proper link.
