A brand wants a username that's already taken, but they hold the trademark. What options do they have?

When a brand holds a trademark for a username that is already taken on Reddit, their primary recourse is to submit a request for a username transfer. Reddit has a specific policy for trademark holders to claim usernames that infringe upon their intellectual property. Creating a new username with minor variations is a workaround but doesn't resolve the trademark infringement. Usernames cannot be edited in Account Settings once created, nor can spaces, emojis, or other symbols be used in Reddit usernames, making those options invalid.
