Aside from that, Youtube is a good platform and maybe a good alternative for gambling streamers now that twitch is banning these gambling streamers.
YouTube is more restrictive when compared to Twitch in this case which is why I don't think your suggestion is really helpful here.
As of now, Youtube doesn't forbid gambling streamers so your argument about being restrictive is somehow invalid. It is possible that the time will come for Youtube to do the same thing as twitch but not at this moment. Streamers whose content are about to be banned on twitch needs an alternative platform and Youtube is one of the best alternative for now. If you don't think Youtube is a good alternative then kindly tell me which platform do you think is much better.
