Somebody posted a part of their TOS the other day having to do with how they handle SSNs that are posted on the platform. It was fairly harmless, basically saying that they would remove any SSNs found; but people were getting riled up about it for no reason in my opinion.

I've seen stuff like it in other TOS, and I'm not sure how often, if ever, it's invoked. If you're using Parler and this bothers you, bring it to the attention of the admins / owners and ask about it. Maybe you can lobby for it to be changed or removed.
