I looked into this a while ago. It seems the best you can do is to try to look the most “average”. All attempts to obfuscate details other than “average” make you stand out even worse.

I used it for a few months. Mostly with snikket. It worked fine for Android but I had problems getting notified on an iphone.

I wear a hoodie most of the time. I don’t mind if you feel suspicious of me; one reason I have a hood up is because I don’t want to engage with random people. Sounds like you would go out of your way to avoid me so mission accomplished.

Those failure rates are nonsense based on theoretical limits. In practice: a few weeks ago I resilvered a 4 disk z1 array with 8tb disks at 85% capacity in less than 24 hours. I scrub the pool every month and it didn’t seem any more taxing than a scrub.
