Are there any restrictions to using publicly accessibly information posted by a company? An example would be a list of the 100 top movies on IMDB, or the 30 most-followed pages on Twitter, or the 5 most-listened songs on Spotify.
Fact are not subject to copyright protection: a list of the top 100 movies on IMDB is a list of facts. There is copyright in the artistic work that surrounds these facts; the font used, pictures, formatting etc. and you can't copy that but if, for example, you used a web API to query the info from IMDB and displayed it as your own artistic creation that is perfectly fine.
