Please post here if you file a DMCA claim against them for misuse of your content without your permission. Their contact information is in their terms of service ([e-mail]) and their public non-profit filing (1), and they declare themselves subject to US Law.

They are a nonprofit, so they have the option of offering each author a tax deduction as payment for content. If you have entered into any rights deal with them directly, you may not have standing to make a DMCA claim; take care not to knowingly do so under such circumstances, as that is likely a crime under US federal law.

Their hosting provider will likely also want to be notified of your DMCA claim, as they may be in violation of contractual agreements signed for their hosting.
