Whenever I see a source and its Pixiv, I know theres like a big chance it'll be 403 forbidden. Sometimes I can google search the artists name and find the Pixiv page like that (if its tagged, or signed on the pic) but other times I have no way of getting to the saucy source.

Does this happen to anyone else? Do you know a way to get around it? Thanks!

Lot of the sources have it link directly to the image instead of the image's page. You can't do that on Pixiv have it viewable. Try clicking Saucenao near bottom of the page.

I think this is mainly a problem with the 'bot' not properly extracting the image source link.

either use saucenao or if you see a pixiv source with a prefix (i4.pixiv i2.pixiv) you can reconstruct the link manually:

just copy the big number at the end of the source link at the end of this link

(you don't have to remember that link, just click a random pixiv image and replace the id in the link)
