One thing I have noticed about the Wabisabi Coordinators List is that whenever I visit it, the source shows that no coinjoins were done using the coinjoin.nl coordinator. Even its history shows 0 coinjoins performed in the last 7 days. It makes me wonder if this coordinator is even working or if it's that unpopular that no one even wants to give it a try. If it was offline for a lengthier period of time, it would surely have been removed from the list.
It seems to work okay but it doesn't get much participants and that means that your anonymity set will be very low in comparison with other coordinators, however that can be okay for many scenarios where you want to gain privacy from non-super-wealthy adversaries, what I imagine is the case for 99% of people.
