Lies, lies, lies...
This isn’t the lottery. There's no reason to hide the identities of winners to protect them. Nobody's going to track them down and break into their house at 4am to rob their shitty Poundland-quality planner. No estranged relatives are going to come out of the woodwork looking for a handout now that they're in possesion of a falling-apart Ponkin Podditiftea Plannaaahr.
People were asked to enter publicly, so announce winners publicly. Otherwise this is blatantly just yet another scam where Ruby announces fake giveaways to look charitable and baits some engagement out of people but never actually sends anything to anyone.
She's also lost track of her lies again. "All winners have already been contacted - apart from for the giveaway on this post!" ...But there's no giveaway on that post. The daily planner giveaways she announced ended 2 weeks ago.
