@pixelfed hey, sorry about this :( Your mail on Mar 18th looks like it was sent to abuse@matrix.org, but didn't get a response because your mail address was bouncing (SMTP 550 5.1.1 Recipient address rejected: User unknown in virtual mailbox table from mx01.mta.zknt.org). We can (could have?) pointed the room alias to a new room if you created one with the right permissions. support@matrix.org is the right place for this sort of support request (although we are very overstretched atm).
@matrix@mastodon.matrix.org at least give a very reasonable and generous response here, but really you should be using your own platform.
Either self host matrix, or because it's a project; you should be using a forum (Discourse or whatever) so conversations are searchable and archivable.
Discord is a cop out, it is lazy and shows you don't care about your community; just what is easier for you and the members that happen to already use Discord. And no, that is not everyone.
