Legality of web scraping

[Lextuga007]

Raised in NHS-R Slack: some websites have disclaimers about what information can be web scraped, and also have tools to prevent users from web scraping (either at all or on a large scale). This would (or should) be set up by the website developer of the page in question and saved in the websites robot.txt file.

Also add something about web scraping patient databases if they are available through the web - this could be a weak point in data access and should be raised with IT teams.
