Every week I'm finding Doman users have created a new organisation, added products and started trials. If it wasn't for the email notifications I receive as an Atlassian admin these things would go unnoticed. I then have to join that new organization, kick the users off, delete all the product trials, wait 30 days for the deletion period and then follow up in 30 days to make sure it has been deleted or needs further attention. It's insane that I cannot restrict users from having this ability. I see why from Atlassian's view is that having domain users with tis ability encourages a wider use or a wider range of product possibility. 

Please Atlassian, we already pay for premium products, pay for add-ons, we control our domain, we control our security, our internal and external users, yet any domain user can come in and create their own space/organisation and add multiple products

Joining the chorus of folks who think it's unacceptable that this feature does not already exist.  It is also unacceptable how I have to create a support ticket to try to expedite deletion of these incorrectly created organizations AND I also have to have sustained back and forth with support folks to convince them that I need these deleted faster.  "We recommend users manage deletion themselves" but we can't just outright delete them.  How can you implement a feature that requires 15 seconds of errant clicking by clueless users but multiple hours of sustained effort from administrators to remove?

Seems pretty ridiculous that issue was brought to attention over two years ago and there still has not been a remedy to it. A lot of companies who use your products are not big enough to want to use the enterprise plan. We are currently using Premium Jira and Confluence and Atlassian Guard. We should be able to stop our managed accounts from being able to create new "apps".
