If people actually protect themselves they don’t have to worry about trickster/negative spirits. If those type of spirits have scared people off from doing spirit work then, maybe spirit work isn’t for them. You need to know what you’re doing in spirit work to be able to do it safely and effectively. I once had to deal with a Djinn which took a lot of energy, but it didn’t put me off spirit work. People need to be aware of trickster spirits coming through so they know how to deal with them.
i will never forgive the witch community for implanting the idea of trickster spirits into other people's heads. even when no one's talking about it as much nowadays (thankfully due to plentiful debunking) the sheer amount of damage it's done to practitioner's sense of safety even now is too much. religion and/or deity work is supposed to be a beautiful thing, and all this has done is made people afraid to explore that beauty. i'm not saying tricksters aren't real, but they're not going to hunt you for sport for wanting to say hello to a deity.
