Beside it are 16,735 user accounts, 130,862 votes, 32,324 badges awarded, 230 tags, 40,019 post revisions and 1,325 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 95 rows.
