Here’s a new type of spam or spoof that’s come up from leaving Youtube comments. They want you to use the Telegram app to contact them to get a prize or something else. It all looks very suspicious. The IP is indeed from Google, and it looks pretty legit, but don’t contact them.
When one WP site links to another WP site, the WP sites communicate with each other using a method called trackbacks. The first site sends a trackback request to the second site. The second site posts the trackback as a special comment, which invites the user to click through to the first site. These trackbacks are automated, making it convenient for both sites.
It is always warming to see the two Chinas, the PRC and Taiwan, getting along. Today they ganged up and tried to break into my site.
188.8.131.52 s China Unicom Shandong, level 10 risk, malware Spam Zero-Day
184.108.40.206 s Hinet Chunghwa Tel Taiwan, known for bots and infected zombie computers
220.127.116.11 s Chinanet Anhui, level 10 risk, malware Spam Zero-Day
18.104.22.168 s Dou shi-BAR Yin chuan Ningxia, level 10 risk, malware Spam Zero-Day
The last one, from Ningxia, looks surprisingly small as compared to the usually huge number of IP addresses for Chinanet or China Unicom, but they are part of Chinanet Ningxia, which is large.
tanyadokterkeluarga.blogspot is a persistent referrer spammer. They use a huge amount of Ip addresses that do not repeat the third octet. It has similar strategies to kosmetik-freaks.blogspot, in fact sharing identical IP ranges. They are sister referrer spammers. Both are not banned by the HTTP_REFERER in htaccess. If you kill one you kill the other, a nice double prize. As with the sister, this spammer runs out of Indonesia.
These are the referrers:
There are some scrapers and there are others that are ridiculous. I just got scraped hard by 22.214.171.124, 209-133-216-182.static.hvvc.us, with 105 server entries and 7 unique user agent names. Excessive, to say the least.

I have sent an email to their ISP, firstname.lastname@example.org.
This kosmetik-freaks.blogspot is a referrer spammer that has been harassing me for quite a long time. I have tried to ban them with an HTTP_REFERER ban but this does not work. My ISP, Site5, will not help me. They are predominantly out of Indonesia. They are pret18.104.22.168
too sophisticated to evade my detection for so long.
The sister referrer spammer is tanyadokterkeluarga.blogspot, which uses the identical method and largely shares the same IP ranges. When you kill one you kill the other. Almost all these UAs are mobile devices, leading me to believe these are mobile customers that have downloaded the same spam app.
kwpublisher.com is a long-time referrer spammer that I would like to remove. I have tried to ban them with an HTTP_REFERER ban but this does not work. My ISP, Site5, will not help me. This guy seems to have a similar method to kosmetik-freaks.blogspot. They seem to be out of Pakistan mostly, but have gone to Indonesia and China. I am now tracking them closely.
Conclusion: Tracked down the code hotlinking to my site. Complained to their domain names provider. Them they disappeared. Goodbye.

Does your raw access log display a host name of “0”, or zero? Very odd, is it not? I have been struggling with this for a couple of months, and my ISP Site5 had no answers. It turns out that one of my spammers, NFORCE_ENTERTAINMENT, puts an unprintable character into their host table, so that when my ISP looks them up, they display the unprintable character in my log as “0”.
Trying to control your site’s spam can be challenging. If you try to ban an IP that is simply 0, or a host name of “0” you will fail, because there is no zero in their host name, but an unprintable character. Ban these guys instead.
no-ptr.as20860.net is a dual Ip spammer with a twist. The originating IP hostname lookup returns three IPs! You’ll need to ban all three, but there’s a lot more. They use IOMart, GB as their ISP.
It seems like this hostname also morphs to numerous IP addresses, making them difficult to track down.
no-ptr.as20860.net hostname lookup 184.108.40.206 220.127.116.11 18.104.22.168
no-ptr.as20860.net not only uses the dual ip spammer strategy, but also changes its host name through many ip addresses, making it double difficult to ban.
