Gelbooru - Exclude Uploader & Limit Character

[DiegoACC02]

Hi,
Sorry for so many questions.
I am downloading images from Gelbooru but many of them I already downloaded from Danbooru.
How can I exclude from the downloads where the uploader is “danbooru” and in the case of the character, limit it only for 2.
Currently I have it like this:
“gelbooru":
{
“tags": true,
“filename": ”[{id}] [{tags_artist}] [{tags_character}] [{tags_copyright}] [{date:%Y%m%d}].{extension}”
}
Thanks in advance for the support.
