We turned on anonymous commenting on articles about a year back after we added Mollum to the site,a Drupal module that checks content to see if its Spam or genuine. For a good while the results were good but over the last few weeks Mollum has been losing the battle and the work of checking posts and deleting spam has become too much. So until the situation improves anonymous commenting is once more off and you need to register to post.
Of course its not that simple either (boo hiss) as the Spammers also love settting up multiple user accounts. Deleting these is also a pain in the ass so here is what we are going to do.
Once a week or so we are going to turn on the ability to create a new commenting account on the site. When its on you will see a register link at the user login page. It will be turned on for a little over an hour at a time so if you want to know when to register you should Follow us on Twitter and / or Facebook. (If Facebook then turn on notifications under the cog wheel when you LIKE the page to be sure of actually seeing when we post). Registration will last as long as the site does so you only need to do this once.
Apologies for the pain but believe me deleting dozens of spam messages a week was wearing me down.
Like most sites we have a major problem with bots trying to post spam into the comments section. While looking for a better solution we are reduced to only on turning on the ability to anonymously comment for brief periods around the posting of new articles. But if you are a regular visitor you can comment at any time by creating an account on the site and logging in before posting. But the Spammers also set up accounts so to reduce the workload of deleting those we only turn on the ability to create accounts for brief periods which we announce on our Twitter & Facebook accounts so follow those to hear when we have that turned on. We do want you to be able to engage with us via the comments and we are very sorry for the fact that we can't find a better way of dealing with spam.
