Every time I try to post an answer to a challenge here, I get this annoying "Are you a robot?" prompt. I've solved it countless times but it still stops me every time I try to post an answer.
How do I make it stop?
That's usually the workaround I do to avoid the CAPTCHA. Because if you explain your program, the spam checker will think that you're a human being and therefore stop the CAPTCHA.
Do you think that typing all that explanation is a nuisance? Hint: Adding just another "Explanation" section without containing an explanation of your program also helps! (Note that you should be editing in the section after you pasted your submission, otherwise it won't work.)
One possible explanation is the speed at which you post. I usually get this prompt if I code out my answer on TIO (which is pretty typical), and then copy the SE-formatted text into the answer box and immediately hit submit. Since your answers are conventionally TIO-formatted, I assume you do the same.
What I typically do is just add a bit -- just a line or two is usually enough -- to explain approximately my approach. I think the prompt appears just because it assumes you're a robot if you open the answer box and then submit a full-length answer within like 1 second.
I haven't tested this, but you might be able to click on the answer box to open it, and then go code in TIO, and then when you finish, come back and paste your solution and submit it. This might get the prompt to not appear because you'll be spending more than half a second between opening the answer field and submitting.
Edit I discarded my draft and then opened the answer box and pasted this answer in and immediately submitted. It gave me the prompt. I discarded the draft and then opened the answer box and watched a YouTube video before pasting this answer in and immediately submitting, and it didn't give me the prompt, so the method in my third paragraph should work.
