My take is that at some point, we will need ID verification online in general to prove you are human. Otherwise it's just chaos out here identity-wise and will get worse like you point out.
It is not about the humans who use AI for posting!
I believe it is more about the bot accounts that gets overwhelmingly annoying... and pollutes this and other places like reddit or other such discussion forums...
Some kind of a verification and vetting needs to happen for account creation.
I agree. But I am also sick and tired of humans prompting some LLM about the points that they want to say and having the LLM generate the response. Online communities will never be the same again.
