My theory is:
Paid work/ads have dried up. If we ignore the weird eBay post, she hasn't done a brand deal since F&F on 14 December. A whole month.
Couple this with January being a month where money can be tight for some people, or people have made a resolution to save.. she's probably not getting many Lumi sales either.
It explains why she's started vlogging again, after previously neglecting her YouTube channel for all of last year. I mean, isn't it weird that you would pick the camera up to vlog on this particular week? A week when you're feeling down and sad and not yourself. Probably because you're panicking about money and need to make some?
