Thanks for taking interest in Brime! We are happy to help you with this.
We have pre-reserved names of popular Twitch streamers, brands, and partners before releasing username registration to the public. One of these names might be yours, to claim & verify you are legitimate please file a support ticket for the "Someone claimed my username" category. This is only for notable streamers, brands, or influencers.
If you are a popular Twitch streamer (affiliate, not affiliate, or partner) notable brand, or YouTuber / social media influencer, we can help claim your username for you if someone has already claimed it without your permission.
We will get back to you as soon as possible and make sure you have ownership of the username registration after verifying you.
