Why do not you just block the ip and forget about them? It is clear that they are not going to contribute constructively.

That's a good question.
Our blocking policy specifically states that blocking is a last resort, and represents a failure of the community. This is especially true with IP addresses, which may be shared; blocking them may also catch legitimate users.
And of course there's the technical issue of determining which IPs to block.
