If my users want to go where I ask them not to go when they have no reason at all to go there, their problem. There are no links anywhere to those dirs, except for the robots.txt. Also, the blocks lift after a couple days. Honestly, nobody ever complained, and I'm sure it stops/hampers some attacks dead on.

View on HN

Users share IPs.

What do you mean 'with bots'? We're talking about anyone at all hitting a link blocking the IP they have.

Some mobile networks have every person on the network originating traffic from the same IP. Some large institutions, universities, government departments, large companies have all their traffic coming from one IP.

This person has effectively created a feature that will perform a denial of service attack on their own website.

The websites I manage aren't Facebook or Google sized. Or even HN sized. I don't see that as a real problem at all.

You see it not as problem, because user don't see you (your sites). As IPv4 are getting rare, many share the same IP. So it's really a bad practice to ban IP for a longer period.

with bots ? If an Ip does not respect the host rules, it deserves to be blocked.

For a start, the entire nation of Qatar shares 82.148.97.69.

And it's definitely not a good idea to run a bot from there.

That's actually not true. A bunch of people in Qatar use that IP though.

Good thing a whopping 0% of my expected userbase originates from Qatar.

robots.txt tells robots where not to go.
