In all seriousness if you own a trademark for zeeen then Twitter will release the name to you.
Username squatting is prohibited by the Twitter Rules.https://support.twitter.com/entries/18370-name-squatting-policy
If your report involves impersonation or trademark infringement,
please consult those policies for instructions for reporting these
accounts. Please note that if an account has had no updates, no
profile image, and there is no intent to mislead, it typically means
there's no name-squatting or impersonation. Note that we will not
release inactive or squatted usernames except in cases of trademark
Attempts to sell, buy, or solicit other forms of payment in exchange
for usernames are also violations and may result in permanent account
Why don't you DM them and ask?
It is a sign of the times though. Any new venture has to do a lot of name-checks to see if they are available. Used to be just the .com, now Twitter, Facebook, etc need to be free too.
