> As of (and including) the 2025-06-30 data dump, Stack Exchange has started including watermarking/data poisoning in the data. At the time of writing, this does not appear to apply to the 2025-09-30 data dump. The format(s), the dates for affected data dumps, and by extension how the garbage data can be filtered out, are described in this community-compiled list: https://github.com/LunarWatcher/se-data-dump-transformer/blo.... If the 2025-09-30 data dump turns out to be poisoned as well, that's where an update will be added. For obvious reasons, the torrent cannot be updated once created.
