“Captcha” Spam Prevention

In order to reduce the lag time in approving comments, we are experimenting with a new “captcha” spam prevention system. When commenting in the ChinesePod weblog, you will now be asked to enter a numerical code hidden in a graphic. Using this system will allow your comments to be immediately added to the discussion, rather than waiting for our Shanghai-based admins to get around (or wake up!) to it. Sometimes the code may be a little cryptic, but we feel that immediately adding the comments will improve the conversation.

    Good idea, works well.

    Great idea, but with possibly unwanted side effects. I tried to enter a comment just now and I forgot to enter the number. Of course the comment was rejected with an error pop-up message as it should be, but after that i could not use my back button, so I lost my text.

    Yeah that did happen to me once, I got the code wrong and lost what I’d written. It’s to good idea to select and copy your text before submitting just in case you lose it.

    Any chance we could have something like this on the wiki? Or just allow logged in users to edit?

    Hello,

    There is quite a lot of spamming on the wiki; The problem is that by simply deleting the spam you help the spammers because throught the revisions there are more links to the various websites that they post on the wiki, and therefore these can get higher in the ranking of the various search engines…

    Apparently the only way to control the spam problem on the wikimedia wiki is by implementing the ‘SpamBlacklist feature’. The info is here: http://meta.wikimedia.org/wiki.....umentation . Could one of tech people have a look pls? If this is implemented we could add the ip-addresses that we want to block to a special page and from there the webmaster could update the SpamBlacklist filter. What do you think?

    A Captcha would be better and I’m sure it’s on its way. But as far as I can find out it hasn’t been released for Mediawiki.

    Spam’s back. Ready to go ballistic. I really HATESPAM!

    Will, how could you say such mean things about spam? Where would we get our cheap viagra if it wern’t for the repectable gentlemen or ladies providing us with the links? I have upped some of the security settings and we’ll see what happens. There are a couple people reporting not being able to post at all, so we’ll be playing around with these settings a bit trying to find the right level.

    True, the value of cheap viagra and weight loss drugs is obviously so undervalued by the mainstream market that they’ve been forced into such drastic marketing measures as spam, but that doesn’t undermine their true worth. The true worth of online direct marketing (as it is more politely called) is in its simplicity and implicit sneaky underhanded illegality.

    What about re-implementing the old Captcha ‘ID method, after everyone got used to copying their text first, it seemed to work pretty well, at least from our point of view. (This in contrast to the newer ID box that was impossible to guess)

    And what about real Spam? That delicious, nutritious, sodium-and-gelatin-packed, square-meat-in-a-can with the nifty key to open it… Why no Spam spam? Buy Spam! Cheap Spam! Gosh, I don’t even know if the stuff still exists but it almost makes me want to go buy a can of it. Just to celebrate the joy of Spam.

    Sorry, 对不起,对不起。。。。。。
    I went a-looking and found a “Spam haiku page”, here’s my favorite:
    As I twist the key
    Heaven will unfold to me
    Pork food of my youth.

    With all the disruption caused by spamming, let’s not forget the real meaning of the “S” word.

  12. 12 Lantian Jul 16th, 2006 at 9:46 am

    “S” is like the biggest import to Hawaii. It is alive and thriving there. This post is a test of the emergency posting system, you will now hear/read the bleeeep.

    Rian the intern,

    According to John you don’t work at ChinesePod anymore. Is that true? Are you the same Rian? Hey, maybe it is true and they forgot to tell you :)

    >>> “This is a good point, and it’s something we’re looking into. I don’t think we’ll give this one to Rian, though. Sadly, he doesn’t work here anymore. (Colleen is filling his role.)

    Ohhhhh, now I get it! This was an old thread and I was too careless to notice. Sorry.

    It appears that after submitting a comment, you have to hit your browser back button twice to return to where you left off. After “captcha” displays its response message for a second (”your comment was/wasn’t successfully submitted”), is it possible to have the system automatically redirect me back to the page where I was? Maybe this is a project for Rian?

  19. 19 Fox Feb 27th, 2007 at 8:22 am

    well, your SPAM filter obviously has shortcomings.

  20. 20 John Mar 7th, 2007 at 8:24 pm

    Just want to see this new CAPTCHA working
