Reposting
Reposting[1] (sometimes referred to as recycling[2]) is a post interaction feature originally introduced in wasteof2.[3] In both wasteof2 and wasteof3, a user can create a repost by clicking the second post interaction button, which shows two arrows creating a cyclic rectangle shape. In wasteof3, "Repost" is also an option in a post's context menu. Pressing this button will bring up the post creation window for the user to write an optional caption. Reposts are treated as separate posts from the original, even if no caption is provided. Users can repost their own posts and other reposts.
Reposting was introduced on September 21st, 2021.[3] On August 5th, 2022, following a spamming incident, unspecified restrictions were placed on reposts.[4]
Repost chains
Following the introduction of reposts, a trend known as "repost chaining" emerged, in which users would repeatedly repost existing posts, typically with similar messages. While wasteof2 would automatically hide reposts after 2 iterations, wasteof3 did not have such a restriction, and repost chains could clog up feeds. This, combined with the dull nature of the chains, lead to a growing dislike of the trend.[5]
