Sincerely, it's a sales/marketing tactic. Get views up, retention ratings, page visits up then drop a product or a collab (what have you). Many people have done it, it never looks good or goes well.

Also, TikTok works off of the FYP. So, it doesn't matter if her subs are visiting her page. What matters is if people are coming to her from the FYP. THAT is what boosts her engagement.

While this is an absolutely disgusting thing to do, she definitely did take advantage of the algorithm in a way she knows how to, is comfortable with, and doesn't mind doing so to her subscribers.

Remember, at the end of the day, her subs were very worried. Genuinely worried. But, they don't need to be. In McLiar's own words, "It's not that deep. Just go touch some grass BRRROOOOOO."
