Places to post my vocaloid songs without getting my data sold?

So, I recently started to work with Vocaloid, but there is an issue:

• NicoNico Douga won't accept Tutanota emails;
• Youtube... I don't even need to get myself started;
• AmeBlog doesn't support videos apparently (and I suspect AI steals from it);

-SoundCloud tracks you.

ETC:

I don't plan on making people pay for these songs, let them be free; Please, suggest a free website; IF POSSIBLE, suggest one that japanese people know.
