The content of academia.stackexchange.com (https://academia.stackexchange.com/), a Stack Exchange question-and-answer site, as published in the Stack Exchange Data Dump of April 2024 on the Internet Archive. The posts table holds 515,352 rows: 148,806 posts (43,792 questions, 103,840 answers, 576 tag wiki excerpts, 576 tag wikis, 17 posts of type 6 and 5 posts of type 7) and 366,546 comments, written between 12 October 2011 and 31 March 2024. Beside it are 147,366 user accounts, 1,570,943 votes, 286,292 badges awarded, 466 tags, 406,267 post revisions and 17,657 links between posts. Every answer keeps the question it answers and every comment the post it was written on, so the threads can be rebuilt. The Internet Archive item describes the dump as anonymised; the votes table names the voter in only 616 rows.
