The more obvious bias is towards Premium subscribers over us freeloaders. The reply-ranking algorithm was a nightmare for a while; they strictly adhered to the rules of gold check > blue check > normal account. It's still not great, but eventually they added enough slack to let normal accounts with good quips outrank 30 paying users saying "lol", and tweaked some things so it's no longer so easy to shill tshirts/whatever by tagging Grok for the gold check double-boost.

But they're still reticent to ban any Premium account without a reason good enough to give up the $8/month. I have some sympathy for trying to moderate in the era of LLMs that can generate perfectly on-topic replies that even take images into context. But I think they need a more targeted approach against OnlyFans bots replying to popular tweets with a standard formula of some sexual reference and an insane claim. Sometimes they're less sexual and more straight up horrifying [0]:

The other bot replies to the same OP are the more typical sexualized sort; they tend to reply in swarms.
