If an amateur can do damage to you, then I have some bad news for you...

I believe the point wasn't surprise that damage occurred at all, but frustration that damage can occur just out laziness/ignorance rather than malice.

Indeed, that was precisely their point, and "bad news for you" is disingenuous as there are many techniques used by incompetent, or just downright unethical and greedy scraper companies which, no matter how robust the target is, can still give it a major headache.

I've witnessed a site being basically DOS'ed due to particularly greedy and aggressive mass scraping attempts.

Precisely this, thank you.
