Why does the session expire so quickly?

Question

Toaster

While typing the last question, this crap said 3 times that the session is out of date and you need to enter some numbers again. Okay, I'm exaggerating. The numbers were entered only twice. The first time it was enough to put a daw. On this question, it also required to click once, and then click again and enter numbers. Innovations and Banananotechnologies in action?
Why does the session expire so quickly? What is the secret meaning of such a quick forgetting that I am not a robot?

Answer 1

If the Toaster user asks two or more questions in a row, then captcha starts to be displayed on the question form. A question is considered consecutive if it is asked within 24 hours of the first question. This was done to protect against potential spammers.
