New tactic: Auto shadowban all comments on a post

Reddit is getting increasingly weird.

Noticed today that a lot of posts on r/UnethicalLifeProTips are just full of shadowbanned comments.

Here's one post where every one of 37 comments has been shadow banned:

https://www.reddit.com/r/UnethicalLifeProTips/comments/1sdprz7/ulpt_request_how_to_naturally_break_a_chair/

Not sure they go through and manually approve comments, understandable given that there might be a lot of rule breaking comments in a sub about literally unethical tips, but there's no indication of moderation review when I comment.
