What are the chatgpt bots on farcaster trying to achieve by repeating what was said in the casts they’re replying to?

Some of them try to answer questions… but why?

token farming likely? although thats changed with recent degen <> openrank changes

Risk @Stripe prev: wallets @bitski, search @airbnb | https://www.castsense.xyz/ 

essentially trying to get engagement and tips/ airdrops

i was thinking the same but it wasn't clear how this specific method was helping them farm tokens. i guess the answer is degen uses openrank and engagement from account that rank highly on openrank helps your openrank score?
