So download and use the original mod then, which was shared twice in previous pages.
BSA files use 7z compression, so can help with storage for large modlists. Mine is close to 1TB even though all textures are on BSA files and I don't store download archives on the same drive.

I dont think the Russian author of Sanguine Mods had bad intentions, he explain his reasons in his profil here. He was silent and not active in this site weeks before his site was closed. So I presume something happened to him or his project at the beginning of September. Anyway I think he is living in his own Russian environnement, far from the Western "capitalism" and "taxes".
By the way, speaking of taxes its a huge problem in England... (from what I hear in the internet).
Edit. What I'm saying its 2 GB BSA limit, not 20. The biggest BSA used by Bethesda has 1.7 GB size.
