Ouija boards are not an ancient and powerful method of summoning spirits, but were a Victorian board game during a spiritualism fad and was made into what we know now by businessmen, not spiritualists. Chances are anything truly dangerous coming about from these would be really rare, and to even summon a spirit would probably take someone with true power behind the board, and not the board itself.
Ouija boards are different than seances and other more formal methods of spirit summoning, and are pretty harmless on their own.
guess whose black ass still aint fuckin with that shit
