How are so many influencers uploading videos with unlabeled filters?

We all know they do this. Its so obvious to me how many of them have beautification filters on themselves because I can see them glitching but as someone who works in Social Media Managment I’m GENUINELY confused how they’re doing this because I know how particular the algorithm is. It doesn’t like it when you post repeat content (aka if you take it with a filter in TikTok, quickly post to the store, or post to private just to download it and repost it publicly) and will ding you. So how are they doing this and not getting penalized?? If I did that for a brand the video would barely hit 200 views. I just don’t understand?

Tiktok also took the ability away to just download the video before posting (sans watermark) so it’s not that. At first I thought they were doing it in Instagram but so many of them are lip syncing to things so that doesn’t track either.
