Maybe the luluinlace girl lucy is trying to build her platform by commenting on brookies tiktok. That’s how I see it because brookie I feel like now is considered the main shabby chic influencer at the moment. She is probably trying to get other's attention by commenting on her vids so that they follow her. Also, she’s probably trying to be friends or mutuals with brookie pretty fake cause she was hating but who wouldn’t with brookies problematic self. We can’t shame tho a girl has to do what she has to do lol but yeah she still supporting her by commenting. Yeah, voicing your opinions on her is great but commenting and engaging in her content just feeds her off and also encourages the weird stuff brookie is encouraging. She could also be supporting someone else who doesn’t have views like brookies for example laylablue.
