DISCLAIMER: I am not a lawyer. Nothing written here shall constitute as legal advice. Although I do my best to ensure the provided information is accurate and useful, I recommend you consult a lawyer if you want legal advice.
No attorney-client or confidential relationship exists or will be formed should you contact me.
If you are an artist dealing with art theft or fraudulent DMCA takedown notices, you do not need to go through this process alone.
Pursuant to 17 U.S.C. § 512(c)(3)(A)(i), I provide a free service for all artists where I can act on your behalf as an authorized representative. Representation does not require I be nor does it mean that I am your lawyer. I am merely a third-party representative.
This will require a signed authorization form with your real first and last name.
By authorizing me to act on your behalf, I will deal with Twitter for you. You won't have to do anything.
Allowing me to file on your behalf also serves to protect your privacy. When submitting a DMCA takedown notice on your own, you are required to give both the offending party and potentially the entire world access to your name, your e-mail, your phone number and your physical address.
When I submit a takedown on your behalf, only your name is displayed on the takedown notice. The address, phone number and e-mail will be my registered P.O. box dedicated entirely to handling sensitive matters such as this.
I will first verify your identity as the real authorized artist. This verification will be done on whichever platform your works are distributed on (be it Pixiv, Twitter, Patreon or so on)
Once that is out of the way, I will send you any necessary documents to sign (via electronic signature) that authorizes me to act on your behalf.
I will then contact Twitter and demand the removal of your stolen works within a timely manner. This will be done via e-mail and a faxed takedown notice to Twitter's designated copyright agent.
Filing a DMCA notice on your own is not as hard as you might think. The major downside to doing this is you are required to expose your name, address, and other personal information.
Additionally, this information may become publicly available via the Lumen database,

I personally strongly recommended you use a P.O. box, non-personal e-mail address and a VOIP number (such as Google Voice) when submitting on your own behalf.
To submit a DMCA takedown notice on Twitter, all you need to do is fill out the following form:

Please be careful and make sure that you provide accurate information when doing so.
