Ah yeah. She and Bree Designs collaborated and created the 30 day reels challenge if I'm not mistaken. Then, Vix and Alice did the whole "30 day reels thing" like a month later or something.
edit: I wonder to what extent Vix (and Alice) have copied this. I know some people on YouTube, for example, are shameless when it comes to copying successful videos. They copy the thumbnail, title, keywords and the script of these successful videos to give them a boost in SEO. Plagiarists is what they are. But I wonder how similar the content of the 30 day reels challenge is vs the 30 day reels thing.
Considering Vix follows solstudio (someone mentioned this above) I think it’s, at the very least, an idea poached from solstudio and breedesigns after seeing their success with it.
Even if you weren’t copying, if you’re aware of a challenge being so similar to the one you’re planning, wouldn’t you at least call it something a bit different or make a point of acknowledging the other challenge?
Let’s be honest, how different can it really be? it’s a 30 day reels challenge!

From what I’ve seen of Vix and Alice’s promos it sounds v similar to the 30 day reels challenge in terms of daily prompts, how tos, etc.
