Can you link the preserved comments or give a screenshot or archive or something?
Absolutely. It took a bit of digging, but I found an archive with some of the comments: https://web.archive.org/web/20230805153327/https://www.1337x.to/torrent/5753101/Baldurs-Gate-3-GOG-Digital-Deluxe-Edition-Multi13-Baldur-s/
It only goes up to yesterday, so some of the recent comments (especially from mods) are missing - but this should provide sufficient evidence. Mods’ combative and defensive comments from today were widely viewed (just look at Reddit), their authenticity is not under question. That being said, comments from Ex0duS5150 are present, proving mods were aware of the listing early on.
User comments provide proof that malware was uploaded (and 1337x mods themselves admitted it was malware in the Reddit response), yet VitaminX remains unaffected on the site: https://1337x.to/user/VitaminX/
