A few weeks ago I received this email:
Subject: [high priority]  Content Removal - SENSITIVE DATA
Our company, AXUR, represents C.......R in issues involving the violation of intellectual property and fraud on the Internet.
C.......R is the only company authorized to use the trademark and owns or licenses numerous trademark registrations worldwide, including, but not limited to the following registration number 825503736.
The trademarks, logos, words and phrases registered by C.......R shall be exclusively used by C.......R and any other use by a third party constitutes a trademark infringement.
It has come to our attention that the reported content provides related content (see attached) to the trademark without having obtained prior written authorization from C.......R . More specifically, this content disclosures SENSITIVE DATA from our client or its customer, creating a Likelihood of Confusion between the trademark and the reported content.
Furthermore, by misusing the trademark on your website, you are also diluting its use, because it weakens the ability of brand identification as a single source of research and may lead consumers to believe that there is some association between C.......R and your website.
Official Website: https://www.c.......rsolucoes.com.br/
Considering the violation of intellectual property rights of C.......R on your website, we kindly request that you remove all content available on the attached URL(s) which use the above mentioned trademark without having obtained prior authorization.
In order to avoid a lawsuit from a federal court, please, send confirmation that this email was received along with your guarantee to comply with the requests reported above.
Under penalty of perjury, we affirm that AXUR is authorized to act on behalf of the C.......R and this notification is in accordance with International Regulations of Internet and Intellectual Property Offices.
Should you require further information or should you prefer to discuss this issue, please do not hesitate to contact us through the e-mail address listed on the signature of this message.
I replaced the real trademark by "C.......R" to avoid receiving a new email asking to remove this blog article :-)
I also received the same email but with a different subject "[high priority]  Content Removal" for the same list but with a different URL: https://github.com/LudovicRousseau/pcsc-tools/blob/master/smartcard_list.txt
ActionsI updated the list of ATR to remove any mention of "C.......R".
I asked confirmation from firstname.lastname@example.org that the ATR list was OK now. I got no answer.
I also wrote them I would blog about it and got no answer as well.
