but the question is still how?

you let your gpu run on a script for 15 minute and you found that one ?

Vanitygen for example:

https://en.bitcoin.it/wiki/Vanitygen

Same principle as mining for bitcoins.

Though a rather more niche market.

It's possible to "mine" private keys to look for ones with a desired string in them, but for more than 7 or so specific characters that gets computationally infeasible, so if you see ones like that then yes they are most likely invented and coins sent to them will be lost.

is there a script available somewhere to "mine" those addresses ?

edit: just saw your link, thanks. I'll have a look

well maybe no one can spend the coins in those addresses.

but take a look here

https://blockchain.info/fr/tags

lots of custom addresses

just a few from that page

1BTC11ifbnvoWY8RJ28nDhZ1SDtj8ooE6a
1MoneySKsyZewy9c7wPyWdX7j6Lxgfazdc
1GERSLqHqpGBGpSFf1UTcH7LfVxWxA4mgC

and more!

They have the money to spend those and they all have a connection to what they are used for

You can generate short custom addresses. This one is mine:

Took 15 minutes of GPU time to generate.

lol, nice

it's a program called oclvanitygen

I can realistically do 8 characters (case sensitive) or 11 characters (not case sensitive), but those will take quite some time to do (a month)

7 characters (case sensitive) would take under 1 day.

I saw that a few times on blockchain.info and now with the kaperlescoin...

how is it possible to have these "custom" addresses on the bitcoin network ?

It's easy to generate a public key.

Nobody has the private to key to that though, so any coins sent to that address are not spendable.
