uBO and POST

On any given website, I understand the purpose of post… submitting credentials for authentication, etc. But other times I really don’t know why it’s there and I’m hoping I can learn a little:

While on https://support.mindbodyonline.com/s/article/205166637-Payments-via-third-party-merchant-service, the logger shows a series of post actions including

https://support.mindbodyonline.com/s/sfsites/aura?r=1&aura.Component.getComponent=1&ui-communities-components-aura-components-forceCommunity-languagePicker.LanguagePicker.getInitData=1&ui-communities-components-aura-components-forceCommunity-navigationMenu.NavigationMenuDataProvider.getNavigationMenu=1&ui-communities-components-aura-components-forceCommunity-richText.RichText.getParsedRichTextValue=2&ui-force-components-controllers-hostConfig.HostConfig.getConfigData=1&ui-self-service-components-profileMenu.ProfileMenu.getProfileMenuResponse=1

Is there a uBO noop-ish type of object which would satisfy the terms of an unnecessary post?

If you block the post method on this page, the page won’t load. I was wondering if there are any privacy issues associated with the allowing the post method on these types of pages?
