Based on what evidence?
As a mod of many subs on Reddit, what I saw killed a lot of the subs over thepast year is the proliferation of spam accounts that repost popular posts indiscriminately within a sub (OC, seller, doesn’t matter) in order to advertise products/websites, etc via pinned posts on their profiles. Plus the Reddit admins allowing “viral” subreddits to spring up on a daily basis by these spam rings.
Most competent mods on legit subreddits knew how to use automod and verification tools to handle sellers, etc. What drove a lot of us mods to throw up our hands and close off subreddits is the fact that we got no support from admins to combat spam/spammers (not the same as sellers).
And of course, at the same time, Reddit banned a lot of long time experienced moderator accounts which then resulted in many niche subreddits to be banned due to lack of moderation. From my viewpoint, the culprit is not due to sellers.
[Addition] - Just old history for reference
I wrote a bot that scanned a posters history, and if it found an of link, it flagged them. Of course it was banned on reddit.
Haha - what a coincidence! I was part of the ones that reported to Reddit admins such bots like the one you wrote so that those bots would be banned 😉 (and they were)

Very well said. Talented OC creators (including sellers) are always welcomed at communities I moderate here (and on Reddit).
And I gladly nuke spam (very well defined by @[email protected] in comment ) and spammers (OC or not). Hoping we get better moderation tools and support soon here on Lemmy
