Found a fake tiktok page with 1.5+M followers

So I was scrolling through TikTok and found this video that I thought was cool. I checked the comments and they looked so weird. So I went back and looked at the comments on every single video and they’re all the exact same. It’s just all a bunch of bots responding and liking each others comments. Some of the videos even have 50k+ comments. I’m sure other people have seen stuff like this im just curious if anyone knows what’s going on? From what I could see there wasn’t any real people anywhere in the comments so whats the engagements even for? Hoe many other TikTok’s comments that were responding to could be fake?Really weird and kinda creepy
