Domain squatters are scum. You're scum. Congrats.
Otherwise, Oracle could have bought every common word domain at the birth of the internet.
I'm a developer and buy domains on whims of various service/fun ideas. I've been interested in domains since early highschool and collecting them is a hobby of mine which has happened to earn me some money from people reaching out to me.
You didn't post about the cool sites you built. You didn't show off your code. You didn't add value.
You posted bragging about "Hey, what if I 'collect' more domains? How much money would that be worth?"
You're not displaying something that most would consider "hacking".
