Keywords were used to determine posts used for the study on these platforms. Such keywords include "coronavirus", "pandemic", "coronavirus_transmission", "coronavirusnews", and more. API's were used, except for Instagram, to collect posts using the keywords to search for such posts. For Instagram, researchers manually looked for posts. They ended up with 1,342,103 posts and 7,465,721 comments from 3,734,815 users. These posts were then separated into "reliable" and "questionable" based on classification by MediaBias/FactsCheck (MCFC) which classifies sources as "Conspiracy-Pseudoscience", "Pro-Science", or "Questionable." Posts classified by the MCFC as "Conspiracy-Pseudoscience" and "Questionable" were placed into the "questionable" category, while those classified as "Pro-Science" were placed into the "reliable" category.
