#Calibre bundles a tool named #ebook-viewer. A default behaviour of this tool is to… modify every opened #EPUB file upon closing, without consent (to store bookmarks and reading progress).

capitalism.party is a paid signup Mastodon instance funded directly by users purchasing accounts for just $5. An inexpensive alternative to free signup platforms, we impose direct economic cost on trolls who want to avoid blocks by creating many accounts. This instance will actively respond to any problematic users.
