It’s also worth bearing in mind that Follow bots don’t even need to view the channel to follow it, so they are impossible for anyone but Twitch to track at all.
View bots can view the stream and count as a viewer without loading any extensions or 3rd party content so again you as a broadcaster would have no way to track them.
And even if you did want to use an extension in some way to do what you’re suggesting, an IP address comes under personal information in the GDPR so if you used a Twitch Extension to collect that without the users consent then you as a developer, and potentially your Twitch channel, would be legally liable for that GDPR violation, and potential breach of Twitch’s Developer Agreement and ToS yourself.
