If one doesn’t, take out the http\\ and www. It may not work as a clickable link, but anyone who wishes to access it can copy and paste it into a browser.
Tried this many times, no workie. But sometimes it posts links no problem.
Although I would generally give this software high marks (retired forum software developer), the spam filter is just a section of junk code which should either be improved or removed.
There’s probably a single line of code which calls the spam filter routine during post processing. If true, then all that’s needed is to find and comment out that line.
I suspect the real problem here is that the site owners are no longer interested in their forum, which is not at all unusual. If the forum died entirely they’d probably just shrug and walk away, as is their right.
As I see it, this really isn’t a code problem at heart, but a publishing model problem. The content standards aren’t high enough to generate conversations that the site owners would be interested in. Almost all forums of this type suffer from the same challenge, as best I can tell. Everybody is really Really REALLY stuck on a single “anybody can say anything” publishing model which they assume simply must be applied to every forum on the Internet.
And so all forums are pretty much the same.
And so the content quality is very uneven.
And so site owners tend to lose interest.
And so technical problems don’t get fixed.
The question we should be asking is, how can this (or any) forum be changed so that the site owners would be excited about participating?
