I don’t think you can get any information on this site. From my experience, any site that doesn’t specialized in magic will have nothing to offer. You are better off searching for sites and groups that practice your thing.
That said, from my experience, the effect of magic most often comes from confirmation bias and placebo effect. If you believe in it, you will experience the effect. I have not seen any concrete evidence that magic works apart from stories of believers. Take it what you will
Not to mention I notice a trend of magic followers falling into conspiracy mentality, stuff like the government knows many things they are barring us from knowing. Soon it becomes less magic practice and more false information and paranoia. This can spiral into a dark place really fast. I would suggest utmost caution if you are to do what you do.
