“I tried reaching out to the Discord.io team on their Discord server, and two minutes after joining, every single channel got manually deleted.”
Discord.io sold custom Discord invite links. Now 760,000 of its users’ emails, billing addresses and pre-2018 hashed passwords are for sale on BreachForums. Its response to a reporter was to wipe its own Discord server, then shut the whole service down. Discord had to revoke the OAuth tokens itself. A vanity URL service held your billing address, and nobody asked why.
