Amenzada con investigar mi IP

Hace un mes y medio abrí una cuenta en youtube, para subir resúmenes subtitulados al español de una serie turca, al subir el vídeo me aparecia que tenía derechos de autor pero este me permitía publicarlo a cambio de que en los vídeos pudiéra aparecer publicidad.
Ningún problema hasta que hace una semana recibi un mensaje de otro usuario de youtube (una empresa turca):
To Whom Concern,
In accordance with the national legislation related to the protection of intellectual property in Turkey, film producers have the exclusive right to authorize or prohibit the sale of the film fixations which the film producers have the rights on by all sorts of wire or wireless means including digital transmission and the communication to the public by any other means. ""ils turk teknoloji iletisim san. TIC. A.S"" Is a lisence company that has been founded to protect and to execute the digital transmission rights of film fixation of the film producers.
While investigating YouTube videos, it is detected that the economic rights of film producers and film fixations under protection ILS have been infringing and have been used (in varied formats like video, flv, mp4, mkv, mpeg, mpg, rar and so on) and communicated to the public including streaming as well as on-line watching, downloading and made available to the public directly or indirectly (through using simple link, deep link, embed…) without obtaining the necessary permission.
For these reasons, in accordance with the provisions of the relevant legislation, within 3 (three) days beginning from the passing of this e-mail to you,

We are investigating all accounts related to the same IP on facebook, twitter, youtube and all the possible places.

You must remove those infringing videos immediately.
Pasados 3 días sin borrarlos, recibí este nuevo mensaje:
More than three days ago, we sent you a message with the URL's of videos shared that you dont have rights to distribute. You must remove them immediately or we take legal action against you, using email data and IP address tracking facilitated by the copyright protection program of Youtube.

Después de este segundo mensaje los borré, pero quiero saber si hay posibilidad que lleven a cabo sus amenazas si vuelvo a subirlos de nuevo, o solo me está amenazando y no pueden hacer nada, decir que vivo en España.
