I tried it doesn't search for a private key, just for an address


Still opening car doors isn't a bad thing, but stealing cars and things inside is a bad thing, don't you agree?

using bitcoins that you don't own isn't good, but guessing passwords is just guessing passwords

IDK, may be some analytics or statistics, or brain training (like guessing passwords)... in any case a lot of usual things (like fork, knife or hammer) can also be used for "bad things".

Bad things? Which bad things? If some site can do any harm to such mighty cryptocurrency as Bitcoin, then the Bitcoin is not so mighty and it's not worth it to keep your money in bitcoins, right?. But it's really funny in fact. I don't think there can be any harm or at least it's very very very unlikely - the probabilty is tooooo looow.

Ja ja, right. The founder perhaps is immortal  .

I've just found the site http://btcdb.info which collects bitcoin addresses to database and shares them. Ja Ja Ja. However it's rather interesting to guess passwords http://btcdb.info/addresses/password as for me.
