Abacus Market is a well established, modern, and feature rich market dealing in everything from drugs, to fraud related materials, to interesting books. Like many markets in 2022 they have suffered DDoS attack after DDoS attack, but through it all they have remained strong and persistent, still offering a great user experience and fantastic support. Currently both Bitcoin and Monero are accepted, as well as all the other features you've come to know and expect (2FA, Escrow, Finalize Early, XMPP integration, etc).
