    I feel like every time someone has ever written a phrase like this (from @matt_levine's newsletter) they get surprised at how creative people can get with e.g. for loops and Maliciously Compliant Capital MMCCXVII, LLC.pic.twitter.com/ubzVvxN7HC

        "You couldn't found a company with a for loop, though." I mean, I work for a company which founds a lot of companies and keeps its nose very clean, so I would absolutely never do that and never provide legal advice to someone to attempt doing that clearly possible thing.

        The classic example of this, by the way, is "Verify this bank account with microdeposits." I have read ~3 accounts over the years, on the public internet, of how companies did not model "We'll send you two deposits of between 1 and 99 cents; tell us the numbers" as abusable.

        Do not ship microdeposits without rate limiting and/or sweeping the microdeposit back. It can end very poorly for you.

        (Incidentally, the impact there to the financial institution is ~0% "Oof, we just ate a $50k operational loss" and ~100% "There are now 50 people involved with discussions about our KYC policies with four external stakeholders who are Decisively Not Thrilled.")

        With a family of four there are about 40 permutations that can be created to exploit this. So a 40k trade. Biggest thing is brokerages started to screen for similar addresses. You’d need 40 P.O. Boxes.

        But this is very scalable. And there are plenty of funds doing this along with other supposedly unscalable and too-small-to-trade trades.

        I heard an (admittedly unverified) rumor that a certain challenger bank was forced to retract its "Get £x when a friend signs up with your referral link" after someone took out a Google ad with their link and made £xxx,xxx.
