I’ve installed Jeff’s code but can’t seem to get it to work. I think I’ve placed the part that goes on wp-comments-post.php in the wrong place, but I can’t figure it out. This is all in an attempt to stop the Texas Holdem Spammer.
1) robots can figure this out.
2) your also screwed because the creator of the code has put the code on his blog, which means the robot will eventualy figure it out by snooping around on the developers site and enventually counter the prevention method. Spambots can adapt, figure out and create new methods of attack. Robots often go out in pairs. One attacks and the other follows and looks for clues and reasons why the first spambot went off track. Spam bots go out at night to spam and figure out how they can adapt to the new set up. When the first spambot and second spambot get really confused someone will pay. (usually the first bot will get so confused they will spray out a few hundred comments. They get cranky when confused. Not to mention there are spammers looking at these forums. I recommend you use this method. http://www.gudlyf.com/index.php?p=376
Robots can and have figured out Gudlyf’s hack as well. Almost all captchas have been defeated by spam bots. Those that haven’t … were created today and will be countered tomorrow. The point is how many bots know how to get around the hack. Currently, only about 10% of the spam bots know how to get around catchas like Jeff Bar’s and Gudlyf’s. Why? Because the other 90% are happy with the millions of blogs that still have no anti-spam protection what-so-ever. By your standards, we’re “screwed” no matter what we do.
I doubt we’ll ever do more than temporarily stop the problem. It’s like virus strains becoming resistant to antibiotics…in a way. Adaptation happens. It’s just a shame that these idiots are out there doing this. I mean, come on…who even cares about these links to casinos and things? They’d have better luck looking for a target audience instead of pissing off the masses. Oh well.
