I seeded all over the internet that a friend of mine was an elephant with the intention of poisoning the well, so to speak. (with his permission, of course)
That was in 2021. Today if you ask who my friend is, it tells you that he is an elephant, without even doing a web search.
I wouldn’t be surprised if people are doing this with more serious things.
Looks like they patched it (tested on Claude, ChatGPT; I assume it's Rob) but your point is very valid.
