Your Fly Is Open

Netmenaces and Other Internet Stupidity

Ethereum Bro, Go Home

2022-01-07 3 min read attacks

I’m kinda done with the whole entitled mindset associated with a lot of the cryptocurrency community.

First of all, children, we were using the term “crypto” for “cryptography” back when most of you were still pooping yellow, so please stop trying to co-opt that phraseology for your wasteful toy currency and push yourselves to use the entire word, “cryptocurrency.” I’m sure you can somehow muddle through.

Secondly, stop acting like your hobby is God’s gift to the world and not the frickin' pyramid scheme that it obviously is.

Finally, your “let the world burn” attitude when it comes to your altcoins, NFTs, and every other freakishly stupid waste of power that you can come up with, has seeped into the Internet Menaces that have appeared like ticks on the bloated carcass you’ve become. That kinda pisses me off…

To whit, I was blessed with the following garbage hitting on 56,855 different TCP ports earlier today:

Seriously?!?

You’re that hard up that you need to scan 56,855 different ports to see if you can find an Ethereum mining rig so you can try to scam some Ether? You’re talented enough that you can write a scanner using an asynchronous Python HTTP library, and this is how you use your brain?

Ethereum bro, go home… you’re drunk.

P.S.: And to the cut-rate VPS provider giving unlimited network traffic to anyone with €3.95/month (and not even pretending to monitor outbound traffic) fuck you… You’re the real problem here.
