I recently went though a round of firewall blocking access from China to my US blog.
The reason for the block was that there were a number of recurring hits that had a very high probability of being scrapper. There is very little, if any, reason for anyone outside the US to have a legitimate interest in my content.
Following the firewall blocking they came in via Google translation. I blocked Google translation.
After that they started using proxies. I blocked them each time they moved to a new one.
Now it seems they are upset. :) This being a new blog a couple of months old, I typically get about 2 or 3 spam comments a day that Askismet takes care of for me.
I just logged in and there was about 40 spam comments today, all from different IP's, all with either Bing, Google, or Facebook as the name link. It is obvious that it was a concerted effort.
I wonder if they are trying to make a statement. It was not my intention to start a war, just trying to protect my hard work.
