Which bank I couldn’t guess, more likely overseas. But I’ll guess the method..

One of them will debank or deny withdrawal to some one or group and it will set off a social media shitstorm. A “boycott” not intended to cause a run will start organically via a viral clip and the social platforms will ban Users first for sharing it and then even for discussing it (ala Covid) and it will snowball from there.

Govs will lean on the platforms to try stop it but that will just be fuel on the fire pissing people off
