I would, but what address should I use? I mean, I could just write to support@twitter.com or whatever, but I would be amazed if that would return anything.

They do not announce an official mail contact anywhere. Looks like they don't actually want to really get in contact with their (potential) users.

reply to my e-mail to support@twitter.com:

> We appreciate you reaching out, but Twitter doesn’t monitor emails sent to this support address. To contact our support team, please submit a request through our online form. We also have resources and articles on our Help Center that might be able to answer your question.

¯\_(ツ)_/¯
