Spam Comment Blocking with Turing # ? do I have a good idea ? (7 posts)

    This certainly isn't an original idea, but has anyone thought of spam blocking with turing numbers ?
    Like what http://www.egold.com and other sites use ?

    Essentially the same php tom foolery that photomatt uses for Titles could be used to make a turing number system.

    The user would have to enter the number as it appears in the png picture or else the comment would get rejected.

    The script uses md5_encode and _decode functions so the verify string is never found in the source code.

    I mean ... this is not meant to deter an "attacker", but it would prevent spam "robots" and such. And a nice feature is that one could still allow anonymous posts and wouldn't have to review every one.

    My blog is not ready yet, but feel free to play around with this system here:

    I just had to change wp-comments.php and wp-comments-post.php around a little, as well as add a couple of hidden fields in the comments form.

    If anyone is interested lmk and I can write up a better "how-to".

    ahh ...

    i see someone else already had this idea for wordpress (which is good cause it means it must not be a bad idea) ...
    at the very least this should block any "non-human" spammers ...

    if i write up my little "hack" i may post a link here.

    basically i just stole some md5-encrypt and md5-decrypt functions off of the php wiki and combined them with the Text2Picture technique used for picture titles ...

    More techniques, especially if they differ even slightly in their methods can only be a good thing for WP users.

    Very true! Not everyone wants to approach the spam problem in the same way, mainly because some approaches can cause inconvenience to their users, or false positive results, or lots of work for the blogger. Having more choices is better so that each person can choose for themselves how to approach the problem.

    The trenscanspammers plugin was very easy for me to install on my site. I highly recommend it. Haven't had a single comment spam since instlling it.
