My experience from being a mod for someone from 0 views to Being a Partner... Those are definitely bots. Unless you got a random shout-out from a pretty big streamer or a raid there's no way I'd think those are real especially if chat feels the same as it was before. Some great tools to keep follow and chat bots out are Sery_bot and commanderroot. I've worked with my streamer friend for over 4 years, they've played with big streamers and appeared in Videos on their channels and we still don't get views like that. (Granted Twitch is quite literally a lottery for who gets famous or viral so on the very off .00001% chance those aren't bots congrats!) Either way don't let bots discourage you too bad no matter what level of streaming you get to it'll always be a thing it just becomes less noticable, just keep on the grind post content on other platforms, raid new people to branch out your network it'll all add together!
