Take any social media app and there is something toxic, mean, snarky about it. Twitter is optimized for snark and shit storms. Facebook has your crazy uncle sharing fake news. Instagram posts are fake and pretentiousness. Reddit has their subreddit drama.
TikTok is just fun. Even wholesome fun.
I tried if I could find one mean tiktok video, but there was not one bullying video. Even if the girl making a dance video was ugly/fat the comments on that were encouraging and positive.
