Conclusion:

Like a physical company-model of the Internet, Poloniex is declaring (and routing) it's presence through an Agent located in that office, Suite 403-A of 1013 Centre Rd, Wilmington, DE 19805.

However, unlike the principle of the Internet (connectivity),

1) your phone calls are not being received there (as undoubtedly you already know if you have tried calling the Corporate Offices of Poloniex to speak to a real person within the last two to three months, which has undoubtedly failed)
2) your tokens are not being held, traded or "anything"ed there.
3) your interests are not being deliberated by responsible Poloniex business executives over expansive, room-filling tables there.
4) your problems are in "no form" being addressed by expert Account Support Specialists there.
5) their "Network Operations Center" is definitely not there.

Despite the beautiful, functional online interface, I cannot recommend Poloniex, as he or they do not have 1) time, nor 2) presence for their customers. "Tristan" is making a confirmed $100+ million dollars a year, but he cannot afford quarter-decent Customer Support.
