Can I process, save user comments (VK, Fb, Twitter, and so on) that are in the public domain, provide this opportunity to other users to analyze them, as well as the users themselves, is this content theft?

Answer 1

Contrary to a common misconception, which can also be seen in the neighboring answers, the concept of "open access" does not have a clear legal meaning and a certain legal force. The conditions for the legality of the use of any information that is published on the network should be governed by a license, which is determined by the author of this information or the copyright holder.
As for the specific question about comments, this is determined by what is written in the user agreement between the social network and users and what is written in the developer agreement. In many cases, the service API rules have very strict restrictions on the use of content outside of the API. This is done specifically so that users can knowingly give or not give permission to this or that application to use their content for certain purposes.
If you are going to massively save yourself comments, etc., without asking permission from users, this, despite the fantasies of libertarians who believe that any information must be publicly available for any purpose, is quite drawn to a massive violation of both user rights and conditions the use of the social services.

Certainly. It's open source :)
Eee ... what? Are you the Lord God? Only the Lord God can analyze users...
What I have posted in open access - I do not mind at all that as many people as possible read it ...

Answer 3

It is necessary to raise an agreement with the content distributor, if user_api provides vk, fb and others, I think they should have this adjusted. If there is nothing explicitly in the agreement, and the data is really freely available, then you cannot violate anything.
Although there are now initiatives in this direction and perhaps the situation will change soon, thanks to the law "on big user data", as far as I know it is currently in preparation.
