I looked up radiosure.com with an online tool and that information says it originates from Moscow which explains the inability to reach it. It could be geoblocked, or just on blackout considering the state of world affairs. Which might explain the absence of Fonzy and other moderators from the different forums. I don't think he can get control of twitter account @radiosure even if he has access to internet. Source: over 2 years ago
