Martijn Someone has the username martijnvdven on Snapchat, and that someone isn't me

Mark Dain Someone has my username on Twitter and they aren't using the account.

🉑 Vincent Leeuw I think you can ask Twitter to hand over the account then. Especially if it has been inactive for a long time.

C4nn4r You haven't been able to request username transfers since 2009 or so. The only current way to get an inactive username transferred over to you is if you have copyright over the name/word, this is how Microsoft managed to get the handle "Outlook" in 2012. There have been cases of people buying website domains like "ancarda.com" for example, and sending Twitter an email from an email address like "admin@ancarda.com" and playing the copyright card, but that doesn't work as often as it used to. Good luck either way OP.
