When you've got someone going the CSP-hosted route, it's critical that you guide them based on current and future needs before you can reference cost with anything approaching safety. I always try to caveat the hell out of the "cost saving" idea. If you don't, it's a great way to have someone screaming at you in twelve months when they did a simple rehost and their costs went up (or, they did a refactor, but, because they did such agood job that it drove up utilization ...and associated "pay as you go" costs). Even ignoring the cost of moving to new infrastructure, if you simply do a 1-for-1 rehost, your costs will tend to go up.
Similarly, even if all you do is get a company to move their development to the cloud, if they fail to adequately govern the usage of the cloud-hosted environment, they can have unexpectedly high costs. Nothing like finding that someone spun up an m4.4xlarge and left it running for three months when they really only needed it for a few hours or even a few hours a day for a few business-weeks.
For further actions, you may consider blocking this person and/or reporting abuse
