Custom Crawler

Please do NOT apply if you haven't read this post in its entirety! I need one or more crawlers to tackle some of these services/social networks from the list below by connecting to them and extracting bulk user profile data, whatever is visible by a logged in user. If you can only do ONE of the services below, that's OKAY - just tell me which ones you have already done or can do. I know [login to view URL] data can be fully extracted, but I don't know how to enumerate all the users in their system. It's fine if you have to take any public/open source work to modify to suit our needs. The crawling needs to be set up so that it can run 24x7 and/or update daily getting fresh/new content to store in a local database. Services: [login to view URL] - CN [login to view URL] - CN [login to view URL] - CN [login to view URL] - CN [login to view URL] - RU [login to view URL] - DE [login to view URL] - ES [login to view URL] - ES [login to view URL] - IN [login to view URL] - IN Please let me know which of the above you can handle!
