Why are these showing up like this you may ask? In their rush to fight spam LJ has created a new filter that're AUTOMATICALLY TURNED ON in ALL journals and communities, which screens comments that are made with 'suspicious links' ie links that are not on their safe whitelist, so pretty much the majority of the internet. There is no noted way to add to the 'whitelist'.
What really gets me is that they didn't inform people that they were doing this until a week after it was done and that it was automatically turned on.
So how do I turn it off you might ask.
That's simple. Go to your Settings, click on the Privacy tab, and half way down where it says Spam Protection uncheck the box next to "Comments containing a link to a non-whitelisted domain will be marked as spam and moved to a special section." This applies to both personal journal and communities and the opinion has to be manually changed in each one.
While I understand how this could be a good idea, I think they went about it in a very backhanded way, and have implemented it poorly. There was no message to anyone that the link has been screened. It's automatically done. This went on for over a week before they said anything about it. There is still nothing in the FAQs about it even. The only way I found out about this way going through the support pages where people were reporting similar issues.
Please share this!
ETA: This links really illustrates the problems.
