Abhishek Chaudhary is truly a child. As someone who runs a software company, I would absolutely never hire anyone who engages in this kind of behavior (especially so publicly), and I hope all future employers are made aware of this behavior.
I like to think that at the heart of all this, Abhishek was genuinely trying to point out the potential for spam, but my god what a shitty way to go about it. It's like Abhishek has never heard of responsible disclosure before. It makes him seem like such an immature "hacker" -- by that I mean someone who has recently learned just enough JS to write a spam bot and now thinks they have the right to "take down" a community, instead of working with them to fix the problem.
In any case, I hope this serves as a lesson to Abhishek Chaudhary about being an asshole online (however I am not hopeful in this regard, as there really haven't been any consequences for his actions). I have reported him to GitHub (for his rude comments here: https://github.com/echojs/echojs/issues/12), freeCodeCamp (where he is an "author"), and will continue to report him in any other communities he joins so they will know about his behavior in interacting with the EchoJS community.
It's funny, I have a little bit of a reputation for being blunt and kind of an ass about things. I'm anti-woke, anti-socialist, pro-libertarian etc, but man, this guy takes the cake.
Note: I did add the part in parens on the title, again I can be a bit of an ass.
It's really kind of funny, all things considered that someone perporting to be anti-spam has created more than every other source combined... and that's after adding, I think well over a hundred entries in the domain blocks and deleting dozens of accounts.
For the most part, most of the spam is actually posted by hand, and one-offs from new accounts, so even then the proposed methods wouldn't do too much, email validation would at least allow for blocking problem email domains, etc. But it's all cat and mouse. At least people are commenting/discussing on here, about the only good thing to come of this.
