I would share their side as well, but I never heard it. This is a violation of their own code of conduct, which requires them to notify the affected person, explain why, and offer the opportunity to mediate the situation. This is not the first time I was banned from the Go community without notice or explanation, and the first time turned out to be frivolous -- the ban was overturned months later with an admission that it was never justified in the first place. Community management in Go strikes me as very insular and unprofessional.
Regardless, I don't really want to re-litigate it here. The main issue is that Google has been DoS'ing SourceHut's servers for two years, and I think we can all agree that there is no conduct violation for which DoS'ing your servers is a valid recourse.
Could try and do both? Drew lives in The Netherlands nowadays. I don't know where Sourcehut is based legally, and I realize the Dutch court system is also overburdened & expensive but it might be worth a shot. I wonder if Drew considered it, and if he'd been able to use the Dutch court system. If Drew needs a good Dutch lawyer, I can recommend Arnoud Engelfriet of ICTRecht (has a blog on Iusmentis.com, legal advice is free if he's allowed to publicize it).
