I have been running a wiki for more than a decade for people to use as they see fit. Its no longer possible because for each person visiting you have ten thousand bots scrapping indiscriminately. Effectively I must pay for a server for the "AI" bros to build LLMs to serve the same information in chatbot format (and collect payment 😡 )
The wiki is now behind a login. But even that will not survive. LLM's impersonating real people (e.g by filling forms) is getting easier by the day.
