Here’s some more blah:
The Bavli was not censored yet in the days of Tosafos. That only happened after it was printed. And then, nothing got corrupted. It was self censored. We took out the “offending” passages. There was the Chisronos Hashas pamphlet which remained around. And, we have Kisvei Yad.
The Yerushalmi, on the other hand, was most likely not even put into writing until much later, it was seldomly studied, and therefore hardly corrected.
The two does copies I posted above show that the Ksav Yad of this Yerushalmi was censored and touched up.
