A forum?. Well, to be honest, I wouldn't be surprised if they point out a cryptocurrency forum one day.
I don't think forum is their main target yet, but they will eventually try to shut down every free speech platforms that talks about bitcoin.
If they don't shut down bitcointalk and other crypo forums they could always try the takeover tactics.
I'm not sure it's a good idea to make KYC mandatory, in case the team is thinking about it.
What KYC?!
They never mentioned any KYC and me neither.
Only thing they can do is to exclude someone from using their service based on IP address.
Personally, I don't think the United States is the problem, but I think you will agree with me that right now everything is orchestrated from that country.
They became just a puppet state, so no they are not the main problem.
Country that is the main source of problem is much smaller and younger than US
