Reiki attunements create energy block?

Hi! I recently saw a video pop on my feed of a woman talking about how when you receive a reiki attunement you are essentially creating a “block” in your auric field that allows your teacher to siphon your energy from you, who then gets their energy siphoned from there teacher and so on. This woman also talks about being an energy healer herself but that reiki is essentially an MLM for energy workers. Does anyone have any thoughts on this? Thanks!
