Data leaks like these happen with some frequency, which is why they are not outlandish.

You keeping data in mind has no bearing on whether or not data leaks are outlandish. You don't seem to understand what the word means, tbh.

No, I directly implied that your real or feigned surprise at this happening makes it look like you don't understand the industry. If you're familiar with the industry it shouldn't be a surprise that this happens.
