The program reports an error and exits directly: "panic: runtime error: index out of range [-1]"
The official said that this type of post is caused by a blacklist, and I think it can be directly ignored.
(Does anyone know what a blacklist means?)

And in this post, the downloader download three extra txt files.

"An existing connection was forcibly closed by the remote host."
I have often encountered such mistakes recently, and they will be resolved in a few minutes. It seems that the website is restricting downloads?

I'm sorry I completely forgot about this issue, regarding the second question, the api has a name field, which in some images named txt is indeed txt. If you rename it with the correct format (png, jpg, etc.) you should get the correct file.
I think this is a special case and unpredictable. I also use other downloaders such as gallery-dl and have the same problem, so this should not be fixed.
