I'm sorry for the lengthy delay before the response. Hopefully we'll get better at this in the future.

I agree - this functionality is justifiable. However, we have many things we'd like to implement, and this one wasn't prioritized for the reasons I mentioned.

I'm sorry we told you this couldn't be done. In actuality, this reached the attention of our engineers quite late. As I understand, you first spoke with our support staff, and then with our community manager, after this thread. You're right about the gap - this is theoretically possible, but it just hasn't been implemented. At all.

It's also not exactly simple: we denormalize data in lots of places, there are plenty of nasty side cases relating to inter-related networks, the data lives in many separate systems, and of course everything is backed up. Getting rid of a single network is more than just a DELETE query. This is lots of code to write and test.

I hope that helps explain our response.
