if you wanna make a spell, do it right. piss in a jar, morning piss is most potent. fill jar with rusty nails, make a poppet of the shit poster you want to be protected from. everyone here has posted their pics, if you can not find a picture of the person, ask caskur, she may have it. put that picture on the poppet doll. add sea salt, seal jar with the wax from a black candle. hide jar somewhere in your home. now when the shitposter posts shit at you, the jar will reflect it back onto them. the shitposter will become constipated every time he spams giffs or replies to your posts.
you do this in secret. no need to post any fancy words or announce to the group that you made a witch jar.
