Your best bet is russian torrent trackers, like rutracker (you'd probably need to use a VPN though).
You could also check the russian social media platform VK for a dedicated group, but I don't know what state it's in (haven't used it in almost 10 years). The owners also have ties with the russian government, so use it at your own riskπ
ALL OF THEM (except for exploding-heads, of course)
