Is data about spammers made available publicly at Mailgun for example to Spamhaus?

AFAIK Spamhaus does not accept spam reports directly:

However I think it's generally a great idea, I'd also love to collaborate with anyone to fight spam.

I would be interested to collaborate, but I couldn't figure out how to get in touch with you via your profile. I tried your HN username @mailgun.net but that address bounced. What's the best way to reach you?
