Issue

https://otwarchive.atlassian.net/browse/AO3-7161

Purpose

Uses a method to fetch recent comments they left on the same work/adminpost to add the content of those to akismet_attributes. On controller, if a comment fails to save because it is spam, it checks for recent comments and mark those as spam too.

So, a couple of things:

• The controller test is failing and I'm not sure why. When the post :create runs and subject.save returns false it should run the code and mark the old one as spam but it doesn't. My manual testing works though (when I force spam? to return true)
• Is using parent instead of ultimate_parent fine? it is easier for sure. the only effect is for comments on different chapters so not that big of a deal?
• Using pseud_id means you can bypass it via new pseuds, is there a way to check pseud.user without another query?
