Comment Spam Prevention and Archive Updating

October 19th, 2013

DChemBark Logo with Ed the Dogear readers of ChemBark,

1. Due to a rash of comment spam, I have decided to add a CAPTCHA to the commenting form. In order for your comment to register, you will have to enter a short code that appears in a hard-to-read picture that appears under your comment info. If you can’t read the code, you can hit the little button with the circular arrows to load a code that is (hopefully) easier to read.

My apologies for the inconvenience this causes. I have tried to resist adding a CAPTCHA for a long time, but traffic on the blog has tripled this year and spammers have targeted a number of posts. If you have any problems with comments not posting, please drop me an e-mail.

2. I am salvaging more posts from the old site and adding them to the archive. Most are from 2007. When these “new” posts are added, those of you who subscribed to e-mail alerts will get a new message. My apologies for filling your inbox with messages about old posts, but I think it’s beneficial for them to be re-posted to the blog where they can be accessed once again.

Thanks for reading,

    Hmm, interesting idea.

  2. McChemist Says:

    Are these CAPTCHAs standard WordPress ones? Cause man, they’re hard to read.

  3. Paul Bracher Says:

    They are from a popular WordPress plugin. I also have trouble reading some of them, but I like how you can reload a new CAPTCHA image until you’re satisfied. And if you mess up, you can just go back on your browser and try again, without losing your comment.

    But again, my apologies. I hate CAPTCHAs, but I really don’t see a good alternative. The last thing I want to make people do is register for an account to leave comments on the blog.

    This is truly a sad day for ChemBark. :(

    On the bright side of things, I found this image in my old files:

    Have you considered implementing a disqus comment system instead?

  6. Paul Bracher Says:

    Can you use Disqus anonymously? (I don’t want users to have to register for anything to leave comments.)

    Is there a blog that’s a good example to see the Disqus system implemented with anonymous users and no CAPTCHA?

  7. Jason Says:

    I believe the blog (completely non-chemistry) has both anonymous users and no captchas. I think with disqus you can choose to put on the captchas as you see fit. That being said, having a system such as that would allow your readers to have consistent names that they can continue to use over time.

  8. Paul Bracher Says:

    @Jason: Thanks. That looks like a really nice system. My gut right now says to stick with the generic WordPress comment system, but I will definitely give Disqus a closer look if spam continues to be a problem.

    Just to tell you that I am glad the captcha isn’t as hard-to-read as the one that Google provides; that one would be a nightmare :(
