White Square Button on Reddit

What it signals here

upvote context

Used in comment sections when someone wants to express a completely blank, unimpressed reaction.

community use

Appears in minimalist design subreddits or UI/UX communities as a discussion prop.

subreddit meaning

In r/mildlyinteresting or r/hmmm it might appear as the subject of a meta joke about bland emojis.

karma context

Likely to earn neutral karma — not upvoted enthusiastically but not downvoted either, fitting its blank nature.
