CURL fails after many runs saying “could not establish connection” or “connect() timed out?

It really could be triggering some DOS-like protection. I would recommend implementing some random delay to make the requests seem delayed by some time to make them appear more "natural.

You should be using proxies when you send out too many requests as your IP can be blocked by the site by their DDOS protection or similar setups.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
