It does not need to be a larger scale event. The problem here is that the forum is in limbo, the members are from very different countries and we are not identified, but in my country, and I'm sure it's not the only one, you could be sued for something like that, it's about 1.500€.
It would be interesting to see if any of the winners (if not all) will create a flag against Ratimov's sudden decision to not do the promised payment.
