I enforced the AGPL on my code, here's how it went (bad)

Can we remove "(bad)" from the title? It's not in the original title of the article, and reading the article the author does not imply enforcing the AGPL was "bad".

It actually went well, I’m not sure why the title is editorialized: he complained and infringers stopped infringing and making money off his work. Job done.

I think it was not too bad, they took it down after you complained. Having the license helped.

I assume you could sue them for having used your software without a license for 3 years. But what would be the amount of damage they'd be ordered to pay you? Some portion of the profit they made by running your software?

In general I wonder what is the remedy when an open-source license is violated. For open source software there are often many contributors, maybe hundreds. Should there therefore be a class-action lawsuit and should they all get some compensation?

What happens if someone violates Linux open source license? Who would sue on whose behalf, who would be compensated?
