Sam2,
(sarcasm on) Stop being so smart. It’s getting hard for people to make hoaxes for money. (sarcasm off)
I also remember that there is a machloket whether Yovel is concurrent with the 7th Shemita or the year after it (4th perek of Gittin). Either way, this is not the 9th year from a Yovel. It’s the 13th.
This is related to Applewhite theorem which states:
(a) People are gullible and will believe anything, even claims that demand painful or suicidal observances;
(b) as long as the claim cannot be checked.
