Seems like a missed business opportunity for Reddit (or acquisition target!). They're sitting on an enormous trove of conversation data that could be better grok'd and structured (for discovery purposes) and monetized through affiliate links without being intrusive to the user.
If reddit did this I'd shut down the sub I moderate immediately. I don't mind them attempting to place ads on the site or otherwise monetize accounts with dumb shit like NFT avatars but if they start making money off of the free content our community's users are creating I'd turn it off immediately.
