It explicitly states:
> (e) you shall not use any manual or automated software, devices or other processes (including but not limited to spiders, robots, scrapers, crawlers, avatars, data mining tools or the like) to “scrape” or download data from any web pages contained in the Website (except that we grant the operators of public search engines revocable permission to use spiders to copy materials from the Website for the sole purpose of and solely to the extent necessary for creating publicly available searchable indices of the materials, but not caches or archives of such materials);
