Any bot CAN go through this MOD; alone, it only blocks the stupid ones. As has been posted before, while this MOD was 100% effective in January 2005, when I first mentioned it. And its effectiveness by itself
has been falling since then, because the bots have been getting smarter...
I monitor what gets input to our registration process, and about 60% of the recent spam registrations attempts have the default values for these variables in the POST... sometimes WITH the new ones we use. I even see some that have every permutation of the agreed/coppa variables that was posted in the Fighting spam registration bots
topic over the past 22 months.
That's why my boards do not rely upon JUST this MOD, and why the original "agreed" is one of the triggers of the Instant Ban MOD.
Bots can get through just about anything. One of "the gang" of helpful people who hang out in the support area has been running tests over the past week on different MODs and their effectiveness against a particular bot that is very popular right now... and found that the two most effective (so far) are changing the Visual Confirmation image generator ([BETA] FreeCap Visual Confirmation 0.0.3
) and this one. He's also testing several of the "humanizer" MODs, similar to your idea, and has not found any to be as effective as the FreeCap VC generator.
