Always read the sites legal documents before you scrape information. Example Linked in does now allow you to scrape data. If you use it in your organization you can be sued millions for the offence. For practice you can try different sites but if you are going to do an official project just ensure you run it past their condition of use.

I agree with @vivekps, especially for students getting into legal trouble for a project can be a risky bet. Also, make sure that you don’t publish without permission any information that you have scraped.

I looked up the site’s terms of use and it is worth it to go through them once(they are pretty restrictive!) -
