I'm not sure when this changed, but lately many of the new users I invite to our corporate instances of Jira and Confluence mistakenly create "products outside <our> organization."
I get a helpful email telling me that this has happened, and suggesting that I look here https://support.atlassian.com/organization-administration/docs/discover-products-your-users-administer/ for my options.
Then when I go to the documentation, I'm informed that I need to get my company to pay for an Enterprise license to have the ability to stop our users from creating these 'discovered products' by mistake. I'm forced to send the clueless newbie an email asking them to cancel the subscription, and they don't know what I'm talking about so I need to do it for them.
Atlassian - if you're listening - this is really, *really* annoying.
