Has anyone had experience trying to claim a username on X or Instagram?

Hello,<p>Has anyone had experience trying to claim a username on Twitter or Instagram and what was the result?<p>I ask these questions because my experience has not been satisfactory and therefore I will explain my situation. I am the owner of two trademarks. On multiple occasions I tried to claim the username that has been inactive and without publications for many years. Although I have the legal rights and supported my motivations, even attaching a copy of my brand certificates and other legal documents so that the usernames can be assigned to me, I feel that the responses from these platforms are automated and nonsensical, they seem be answered by a bot and that even though I provide the required legal documentation, they do not review it either.<p>The truth is that as an entrepreneur, it is frustrating not to be able to achieve the objectives in favor of my startup. These platforms prefer to keep the handles inactive for years instead of giving them to others who do have a use for them, and the platforms do not see that those of us who are serious about a business can even invest in advertising through these platforms.<p>I am aware that the rights to a handle&#x2F;username are served by the first person to register it, and as long as its use does not infringe a previously registered trademark. However, I understand that if the username is inactive for many years, these platforms should reconsider their policies and be more flexible with those of us who wish to give it real use for our businesses.<p>I have also tried to contact the current owners, with no results either.<p>Any advice is welcome. Thanks for the support.<p>Best, Carlos
