I'm building a website that mainly relies on data scraped from a sport federation. The data scraped probably represents more (or a lot more) than 10% of this sport site. Most of my website relies on this data, i intend to reformat the data, make statistics among other things.

I was wandering if this is all legal so I checked previous legal actions and especially the terms and conditions of this website and the following caught my attention:

You must not:

• republish material from this website (including republication on another website);
• show any material from the website in public;
• reproduce, duplicate, copy or otherwise exploit material on this website for a commercial purpose;

You must not conduct any systematic or automated data collection activities (including without limitation scraping, data mining, data extraction and data harvesting)

So I'm guessing their terms pretty much forbids me to do anything with what I scraped. Few questions:

Does their conditions hold in a court of law? (the site specifies that they abide by Swiss law) What if I'm not even swiss?

How risky would it be for me to publish anyway? I'm guessing that monetizing my content with ads would be even riskier?

Should I contact them and work some kind of arrangement ?
