You can forget the Telegram contact, (based on what Shiban said).
(Seriously) Your best bet would be to email them at:
https://endchan.org/.static/contact.html
Especially if discord and irc riz are not good options for you.
They both seem really busy… So make first contact.
A temporary/secondary optional VPN you could use is TunnelBear VPN, LLC.
It has some free data use monthly*
Available in app stores , etc
https://www.tunnelbear.com/features/
It a good extra option.
For now posting is only possible on EndChan Magrethea version as all other has be locked due to spammer, can only do moderation via the .org pathway. For now , best to leave Bunker threads locked except that "practice thread" as that's a good means of testing. The spammer is still spamming to some extent..
