3 reasons mostly.
1. Nobody actually gives enough of a shit about Reimu to obsessively defend her like that.
2. They keep putting in bits of information that's not publicly available, (Like how she specifically spammed /nijien/ telling Bari to kill herself on April 14th, Bari's birthday, and how she'll never get into Niji, etc. when nobody had heard of her before.)
3. Every single post was deleted at once, which only happens if it's one single person who got their account banned.
This is on top of Reimu's history of being obsessed with 4chan and /vt/ specifically. Reimu comes here so often that her most visited sites show both /vt/ and the /vt/ archive site.
