No. It's nostr:npub18994crjwnldrukwym5lz3y2nae84s84v20m2rkngtjnyg549lr6qvxmd6m - not sure what the rationale is. You can find out domains with higher limits to join and then follow a bunch of people from NoAgendaSocial and the instance itself. Or just use both accounts and boost toots from elsewhere (assuming this doesn't break some etiquette)
