We did not used to have a definition of Paralyze, and Ignore is actually a viable substitute in some ways when trying to word special abilities so that people understand (which was that play-as project's goal).
As stated before, if it changes what a card does and is not listed on these boards as an official errata, those Play-As statements are not official.
Palsy is a paralyze, and the latter part of its ability is now clarifying text since we have a definition.
