An IP address linked with the website being accessed is already PII.

When serving content, you're by necessity linking it to a website that's being accessed.

For example, if grindr.com had a display in their offices that showed the IP address of the request that's currently being handled, that's not saving or publishing or linking the data, but it's still obvious PII.

You are not sharing with a third-party, but that sure falls into processing and publishing it.
