"suggested them" can mean two things in English: you recommend them, or they are examples. I mean the 2nd case. I understand that you were not ever recommending your examples. You were suggesting them as examples why snapshots in general are bad.

The problem is that your examples are crap. They're bad examples because they would break the system, therefore no one would actually do snapshots-rollbacks per your examples, unless they wanted to blow up their system.
