In GIGAZINE, there was a time when I reported scattering about blogs of automatic generation once in the past, but recently the adult system has become stronger, so I will also put emphasis on those reports.
By the way, in most cases, such a spam blog is almost certainly deleted and disappears when reporting to the blog management service, but in some cases it may be opened again, it will be scurpable. In such a case, if you inform all of the known spam blogs at once in a blink, a malicious user is identified on the blogging service side, a warning or the like goes to the provider to which the spammer belongs, and finally It seems that there are times when it is subject to withdrawal from membership.
The number of spam blogs on the Internet is very large, but last year, I have noticed that we continue to report indefinitely that "there are few spammers actually doing super malicious things". In other words, once you get informed and receive a withdrawal from all the providers you have, you will be unable to connect to the net, it seems that spam will decrease from the whole net at once in a period until joining the next provider.
Therefore, if you find a spam blog it seems better to report it as if picking up garbage falling on the road.
