This is an unfortunate double-standard in the DMCA -- to file all you have to state under perjury you are acting on behalf of the party whose work is claimed to be infringed. The claim of infringement itself does not have to be stated under penalty of perjury.
On the other hand, in the counter-takedown notice you have to state under penalty of perjury that the material was removed by mistake or misidentification. It's a scary thing to do unless you can afford a lawyer.
At the current levels of volatility it's probably not a good idea to keep a lot of open orders - unless you can watch the markets 24/7. Automated traders would likely wait for a significant price change and then execute a market order or just place an order on very short notice.
Both Alex and I are from Toronto (we are the engineers on Hyperlapse). I shot it on a little visit at the start of the summer and it became our go-to demo. That water taxi is particularly windy, bumpy and beautiful.
I'm surprised to find this reply at the bottom, as it's the most important point here (besides lack of jurisdiction): the DMCA doesn't require anything from ISPs, it grants them immunity if they follow the procedure. They're allowed to ignore a takedown, they are just liable.
Unfortunately this is something that is intentionally designed to suck in almost all cases. It's even hard to pay someone else to do the canceling for you since you're generally required to offer up a lot of personal info to verify that it is in fact you that wants to cancel the account. I've personally had this range from phone number all the way up to SSN.
Read your contract. It will almost certainly have a section on cancelling which will give a postal address. Write a short letter with your account details and whatever else the contract says to provide, and cancel by mail. It is faster than using the phone.
I've been doing this for years and it always works. Pay a tiny bit extra and get signed proof of delivery. This is helpful when the company 'accidentally' loses the cancellation. It's good enough to beat them in court and god help them if they ding your credit and you have proof you cancelled (and that they received your cancellation letter).
