An honest question to the members of this sub re: moderating obvious fake accounts

Edit: see? They're even in this thread. Here's another.

Please consider this recent post and its comments:

https://www.reddit.com/r/btc/comments/q8kszk/cloud_protocol/

First off, the post itself is off-topic spam, and should be removed for violating the rules in the sidebar. But setting that aside....

100% of the comments are from brand new zero-karma accounts making their first comment ever. All of the comments are zero-effort. This is clearly paid comment spam.

I recognize that this is merely "my subjective interpretation" of these accounts, but I ask the community in all honesty, why are mods allowed (even required) to use their subjective interpretation to remove top-level posts that are "spam" , but not allowed to remove these obviously fake shill accounts?

Why is one subjective assessment "moderation" and the other "censorship?" Why do we tolerate obvious paid shill accounts, but not obvious paid shill posts?

This is an honest question and I would appreciate honest discussion on the topic. Thank you.
