Also worth mentioning: as long as you're scraping facts and combining them in a novel way, copyright law is much less relevant.

This opeartes in what I consider a legal grey area. Don't make it obvious that you're scraping, only scrape public information, transform the results, proxy your requests, all contribute to lowering the legal profile (which is my only concern, as I feel I am acting within my own ethical limits).

Eek. This is only kinda true. You ought to talk to a copyright lawyer and get a handle on derivative works and data compilations. You can get started by reading this Supreme Court case:

Feist Publications, Inc. v. Rural Tel. Service Co., 499 U.S. 340 (1991) https://casetext.com/case/feist-publications-inc-v-rural-tel...
