You can always choose to cut out the middleman altogether and just source the show directly from Toei Animation. I recently discovered a site called
taod.jp, that offers online streams of Toei Animation's properties on a paid rental and subscription basis.
Sailor Moon is on that site, in Japanese audio but without subtitles. The site is intended for domestic use in Japan, but to my knowledge it does work outside of Japan as well, at least for now. So if you can somehow send money to that site from overseas, you can officially support the show to your heart's content.
