When a company gets large or important enough it realizes that it has to follow some inconvenient laws.

In the US there's OFAC (https://www.treasury.gov/about/organizational-structure/offi...) which lists individuals and entities that companies cannot do business with. Implementing these rules is a nightmare for companies so they use a 3rd party services which produce a huge number of false positives. Middle eastern names tend result in many false positives.

My guess is that Slack is scrambling to clean house ahead of the IPO and they don't have a user friendly way of dealing with this. In fact most companies don't. This is the same crap that bites people who inadvertently end up on no-fly lists with no way to get off.

Don't like this? Call your representative. Build a better way to implement OFAC and similar laws.
