Yea, they have ignored DMCA notices but let's see what their Datacenter(limestone) think about it

DMCA Complaints

Limestone Networks handles any and all DMCA complaints very seriously, and will investigate them. Limestone Networks reserves the right to pursue civil remedies for any costs associated with the investigation of a substantiated policy violation. The first violation of this policy will result in an 'Administrative Fee' of $250, and if severe enough, potential termination of the server or account. A second violation will result in an 'Administrative Fee' of $500 and will also result in the immediate termination of the server or account. Users who violate this policy agree that in addition to these "Administrative" penalties, they will pay "Research Fees" not to exceed $175 per hour that Limestone Networks personnel must spend to investigate the matter, to be charged only if claims are found to be valid. We take DMCA Complaints extremely seriously, save yourself and us the trouble.
