Thanks for linking to this post, very informational. I can see lots of effort being put into finding these non-value add posts.
Question: When these posts are removed for spam, do the comments also disappear from people's comment history?

Ie. if I review the comment history for someone and I can still see the comment, does that mean the posts are not deleted for spam?
In that case, I have less to think about when reviewing an account. Otherwise, I also have to analyze under which post the comment was made (which is more time intensive)
