Reddit User's Active Subreddits by Username (English)

omnial/reddit-user-active-subreddits

Takes a Reddit username and lists the subreddits Reddit shows that account as active in: each community's ID, name, r/ name, type (public or restricted), NSFW flag, subscriber count and a short preview of its description with links removed. The list is null when the account does not show its active communities.
