Some of us have a "gut reaction" to false seers. Some of us figure out who is false simply by reading statements in light of Church doctrine and comparing falsity with truth.
But, I have one really clear message for those who are susceptible to false prophets, false seers.
Obey the Church.
If the Church has not approved something, do not follow that person or set of events.
There are plenty of approved apparitions and private revelations. One does not have to go after what I call "the flavor of the month".
Remember the words of Our Lord Jesus Christ.
