Great post @MeganB!! Our work online whether it’s on social media, blogs, vlogs, or even making memes- that’s all part of the Craft too.
I think there’s a delicate balance in sharing our personal workings (such as altars, grimoires, spells, etc) while following the pillar of the Witch’s Pyramid “To Keep Silent”. 
Each thing we share is an invitation for all sorts of external influences and whatever you can do to stay protected counts.
I like to keep black tourmaline near my desk when I’m on the computer. Having a magickally inspired desktop background or screensaver can reinforce that too, or the decorations and wall art behind me right now. It all helps me shield myself. However I do try to stay as far away as possible from some social media platforms which can be pure toxicity.
