Ask streamers to confirmation receipt of DMCA strike emails
Request that streamers confirm they have read their DMCA strike notification emails. Streamer's inboxes, right? Too many instances of that first notification being missed (and the next two can come in super-quick succession). If they don't reply, spam them or ping them when they access the platform - it's in their interests!
Yes, it's up to streamers to read important emails from Twitch but at its best, technology can help us live better lives.
