Moderators of the subreddits in reddit are normal reddit users (normally) compared to the moderators in TikTok who I presume are selected by the company and on payroll (or contractors maybe, I seem to recall Facebook uses contractors for this)
What difference does it make? People are moderating content that they want to seen or not want to be seen.
No different than the editor of a newspaper or television show.
Paying their labor seems to be a respect in which TikTok is better than reddit, not worse.
I don't think Reddit gives moderators instructions to remove content if it indicates that the poster has a list of undesirable characteristics like being fat or poor.
