8:12–cv–00020, 2012 U.S. Dist. LEXIS 47686, at *18 (D.Md. Apr. 4, 2012) (“A majority of courts ... have specifically held that the properties of BitTorrent are insufficient to support joinder.”); In re BitTorrent Adult Film Copyright In- fringement Cases, 296 F.R.D. 80, 90–91 (E.D.N.Y.2012). As with personal jurisdiction and ven- ue, AF Holdings could have brought a suit for which it had some reasonable basis for believing that the requirements for joinder would be satisfied. But given its decision to instead name and seek dis- covery regarding a vast number of de- fendants who downloaded the film weeks and even months apart—defendants who could not possibly remain joined in this litigation—one can easily infer that its purpose was to attain information that was not, and could not be, relevant to this particular suit. Such use of the discovery procedures is prohibited. IV. Accordingly, we vacate the district court's order and remand for further pro- ceedings consistent with this opinion. We leave it to the district court to determine what sanctions, if any, are warranted for AF Holdings's use of a possible forgery in support of its claim. *8 So ordered. C.A.D.C.,2014.
