Anyone have experience getting a (legitimate) Telegram group unbanned?

The Ponder chat (support, feature requests, etc for an open-source tool) got banned last night. No idea why. We have 600+ members, it's a key support tool for us - appreciate any leads immensely.

Building ponder.sh. EVM, TypeScript, open-source enjoyer.

Had my account reported for spam awhile ago. You have to keep trying with support, there's no other way. I've been told that paying for premium helps expedite things but I really don't know.
