Yes, anyone can claim a drop from the Twitch promotion and there will be a limited free-trial for Overwatch this week so players can try out the beta.
The Overwatch 2 PvP Beta will begin April 26th at 11am PT and is scheduled to run through May 17th (date subject to change based on testing needs).
just remember to use that report feature
If it does not work?
Just leave voice/text chat 
Just play for yourself and have fun!
that is the exact mindset those who say kms and give threats want you to think
that its pointless to report so why even do it
The in-game reporting tool should still be available in the beta build.
Well I guess that answers questions of whether or not they’re testing the servers if they’re basically opening it up to everybody….guaranteed drops means they don’t care how many join
ow2 beta guaranteed with 4hrs watch time. feelsstrongman clap. can a lvl 3 post the ‘‘totally redeemed yourself’’ clip from dumb and dumber.
Not exactly, remember this is only an eight-hour promotion window and you must watch four-hours. This is a very steep requirement if you think about it.
In the theme of watching streamers, i’ll better watch the gameplay muted because not hear their bias crap.
who knows you may get lucky and find that one guy/girl who just plays the game and gives good commentary or who uses it to tell stories
I comment something, i get banned in less than 1 sec.
Be careful, I’m not sure if it counts your progress if you mute the stream?
Not 100% sure though. Someone who’s done this before will probably know 
I’m just gonna chill and watch Fitzy, so all is good!
Is it four hours continuous?
Years ago i was used to watch OWL and OW streamers in twitch and the official OWL page for tokens and drops.
Certain web browsers may stop reporting to Twitch if you mute and hide the stream. It is strongly recommend to keep volume playing and keep the video in view to ensure that does not become an issue.
Accumulative across any eligible streams you watch.
Right! Thank you for the clarification!! 
It’s definitely not required since you are not actually giving up money for the chance at entering. And if it’s not an automated system, which I don’t think it is, then there are no fixed odds to disclose anyway.
And if there is a limited number of beta access, then your odds are just going to depend on how many people are watching.
I spotted an inconsistency in the drops time window between the article on the Blizzard website and the Twitter post:
Which is the right one? I’m going crazy. xD
