Tensions are rising once more at Reddit with fresh protests against the company’s management, and the company expelling rebel moderators.

Earlier protests have seen many of the site’s communities—or subreddits—turned private for extended periods by volunteer moderators, effectively taking those communities offline. Others have amended rules to mock the site’s management. For example, r/pics is only allowing users to post pictures involving the comedian John Oliver.

Now the sites users are continuing to display their anger on Place, an interactive artwork in which each user of the site gets to place one pixel on a huge graphic. Last year’s Place turned into huge collaborative artwork that was sometimes disrupted by organized factions trying to overwrite each other’s artworks.

This year—rather predictably—users are working together to deface Place with artwork and messages that attack the site’s owners. Earlier today, Place was showing a graphic of guillotine, under which an avatar of the site’s CEO was placed.
