I don't care if my personal information was leaked. I followed discussions, posted a comment or two like, "What evidence do you have for that?" There seemed to be tons of other accounts that did the same, along with accounts by obvious Lefts who were there to troll. I highly doubt there will be blowback for the kind of participation I did.
I am absolutely a privacy advocate. However, in the case where the continued existence of our democracy hinges on rooting out violent domestic terrorists, I am willing to make tradeoffs. At this point, you should think about Parler as a jihadi forum for rednecks.
