I did find that, while running a financial startup, I was able to significantly reduce attacks on the server by disabling access from Russia and China. Not saying that's happening here, just my experience. That was a while ago so I'm sure things have changed since then.
Startups don't have enough free time to analyze individual ASNs, because they don't have enough people for that.
That and financial businesses usually don't operate outside their host country anyway. Though you do want your customers to see their accounts when they're traveling.
Thanks for your reply! I hope this is the real reason of blocking. If that's not the case, that's at least not effective. Less effective than idk placing a banner in the header or whatever.
I mean I eventually read the article. Sorry for that. But we're at "Hacker News", sporting hackers ethics, aren't we?
