ShillGuard – Reddit Shill & Bot Detector

See if any Reddit user is a shill or bot — suspicion score, promoted links & hidden activity, right on the page.

ShillGuard tells you — instantly — whether a Reddit account is a genuine user or a shill, bot, or coordinated promoter, without leaving the page. A shield appears next to every username on Reddit. Click it and you get: • A suspicion score and clear verdict (Looks Legit / Suspicious / Likely Shill or Bot) • Account age, karma, and how much of their content looks AI-generated • The domains and products they repeatedly promote — the #1 shill tell • Copy-paste and cross-posting patterns across subreddits • Their recent tracked activity, linked to the original posts The difference: ShillGuard is powered by SubSignal's index of Reddit activity — so it can surface behavior even when an account has deleted posts or hidden its history. You see the pattern, not just what's live right now. One click also copies a shareable report link you can drop into a comment to call out a shill. Perfect for moderators, community managers, crypto and SaaS communities, marketers vetting influencers, and anyone tired of astroturfing. ShillGuard requires a SubSignal account (ShillGuard plan or higher). Manage your key at https://subsignal.ai/user/api-keys
