 ## Data Source
 
-**Pushshift Archive**: [Pushshift](https://the-eye.eu/redarcs/) is a social media data collection, analysis, and archiving platform that has collected Reddit data since 2015, offering real-time updates as well as historical data dating back to Reddit's inception. I downloaded the relevant files from this data by predetermining which subreddits to work on and used Zapier to split the file into manageable csv files. I've included a python file that demonstrates how I filtered those csv files. I also filter the data based on top posts (by score) and from 2014 onwards.

 - Author Flair Text: Text of the flair attached to the author's username in the context of the subreddit. Flairs can denote specific roles, achievements, or statuses within the subreddit community.
 - Link Flair Text: The text of the flair attached to the post itself. Subreddits use link flairs to categorize posts, indicate post status, or convey other information.
 - Image (PIL object): For datasets including image analysis, this could be a Python Imaging Library (PIL) object representing an image associated with the post. This allows for direct manipulation and analysis of post images.
-- Image Text: A generated feature that might represent text extracted from an associated post image using techniques like Optical Character Recognition (OCR). This can provide additional context or content for analysis, especially for image-heavy posts.
