why do you think Tituba is an easy target for witchcraft obligations?

Tituba is Parris' slave from Barbados and hence becomes an easy target to blame. Tituba is black and foreign which makes her an outsider in Salem.Tituba was with the girls when they danced and attempted to conjure the spirits of Ann Putnam's dead children. She is the first person accused of witchcraft and likewise the first person to accuse others of witchery - particularly when she discovers that the easiest way to spare herself is to admit to the charges no matter their truth.
