We all know what are the spammers but tries to fight is another matter. Worpress not immune to these ongoing attacks, for example, by receiving the comments. While there are many plugins so far not very effective at stopping access from China, for example.

The most effective I could do so far is to block IP addresses.

Other information that can make us suspect is when we appear in the statistics a message like:

Unknown robot (identified by 'bot*')

This must be careful when blocking bugs that may be well intentioned but it is always good to know your IP address and try to prevent that do not consume much bandwidth.

Another issue that I am reviewing is theHOTLINKING

By use of the file .htaccess I managed to stop a high percentage of robots access from China and Russia . So far the list of blocked IP addresses are:
