A new wave of automated spam has emerged — one that looks harmless but signals a shift in how bots operate. These form submissions, filled with random strings of letters instead of links or sales pitches, are not typical spam but automated probes testing how websites handle validation. This article explores the growing trend of “intelligent” form bots that mimic legitimate user behavior, bypass traditional validation logic, and challenge our assumptions about how spam operates — and how we should defend against it.

If you regularly use Google Tag Manager (GTM) to set up event tracking for form submissions, you've likely encountered forms that submit using AJAX, which can make capturing successful form submissions challenging with standard methods. Unlike traditional form submissions, AJAX forms do not trigger the typical submit events, making it difficult to track them using straightforward GTM configurations.
