Picking of quality Instagram user base from open sources with your criteria: subscribers, subscriptions of specific users, hashtags, geo-tags to competitors. Without commercial accounts, bots, "dead" and blocked accounts - only real active users of Instagram.
The collected Instagram user database can be further filtered by the number of publications on the account, the number of subscribers/subscriptions, the last activity of the user, by the number of likes, by stop words (this will help to exclude, for example, manicure-pedicure accounts, makeup selling any hat) blacklist of accounts, to whom not to subscribe.
Data can be represented as a URL or login (or with options, for example, login + number of subscribers), and also as a digital user ID.
