All you really need to read is the language, they aren't people they're 'shady domain land grabbers'.

You can tell from the language that the OP knew of an opportunity to buy mispriced assets and/or renew their domain, and having failed to take the opportunity is now upset at others having taken the opportunities they missed.

You know the kind of people that couldn't be bothered to spend $90 for a 10 year registration and now have to pay a few hundred to get a domain back they wasn't worth $10, or clicking the 'auto-renew' button to them.
