What are the ways to enrich data about users with their profiles in social networks?

Question

Marketing

Hello!
I am interested in such a question, does anyone know the developers or maybe he himself was engaged in such a topic as enriching data about users with their profiles in social networks in real time?
An example of what I'm talking about is the application "Caller ID and Contacts: Eyecon". When you call, he pulls up the data about the owner of the cell number and you can see his profiles in various social networks.
There are two questions:
1) Has anyone dealt with a similar topic, if so, how was it implemented?
2) Does anyone have contacts of Russian companies or developers who could tell in more detail about this topic or deal with it directly?

Answer 1

I practiced about a year ago for a long time. Created a bot screening system by identifying profiles in social networks and many other sites from visitors from various traffic sources.
That is, I buy traffic, for example, a popunder, put a url with a label, and launch it. Further, with the help of my system, I see the contacts and accounts of each person who came with the label that I put in the url.
Social networks actively resist all methods of tracking and there are no legal methods, in this regard, building your own system for personal use becomes unreasonably expensive.
But there are BigData services from which cookies with id have already been recorded for millions of Runet users, and they have a lot of information on users. Unfortunately, they are quite expensive, but if the business is sufficiently marginal, then this is a great opportunity to improve conversions and explore traffic channels.
I don’t think that someone will tell you the specifics about this topic, since all methods are quite “black” and quite expensive to share.

there is no real time there, there is a base for the
last two years, this is all on the verge of legality, so you won’t use it openly
