OP. I noticed some coated UpWebm very well.

chan.sankakucomplex.com There is no Guro content limit

Rule34hentai.com Speed is very fast. You may not be able to set GUro Tag or any tag - your Webm will become private and you can link well.

rule34.com is a viable option that everyone knows.

A personal Twitter channel - remove cmt and Share, any of your Guro content will be yours personally (they allow it).
Chifudoon has a twitter page that you can see https://twitter.com/EMOGORE_0210

I think these places are good places to Update your great long videos. And they're fast as well as easy to find. Your works will not be afraid of being lost, or deleted arbitrarily. I still think Twitter and chan.sankakucomplex.com are the places
