The hack here was to obtain credentials from other website(s) and then try them on the Roku website. If you use separate passwords at each site, then you are safe from this. If you use the same password at multiple sites then you are not safe, even if they didn’t get around to trying your password at Roku. Ie: they could still have your password – there is no way to know until they use it.
If you’re not sure, then change your password and don’t use the new one elsewhere.
Banned but back. Because why not?
