They use LLMs to post, they leaked their prompt once a few weeks ago.
It's not a crime to cross post from reddit, but it should be against the rules to use scripts and LLMs to post reddit content over 1200 times in a month on a single account. It's more than that if you include their other two accounts.
As you see by their reply to you, anyone that points this out gets called a reddit "agent" or employee by the operator. They weren't smart enough to avoid doing so on their other two accounts, which shows they operate those other two as well. That is the problem I have: they put no effort into their posts, fill the threadiverse with an incredible amount of reddit slop through multiple accounts, and the vast majority of their "engagement" is calling users reddit agents. They get away with not having the bot label because they make comments seperately like the reply to you.
