I was having visits from a Japanese IP that is registered both here and at Honeypot. (150.70.84.24 is registered here once)

IP's in the 150.70.84.151, 152 and 24 (comment spammers) range were consistently popping up when I visited my site to work or any reason.

Looked up the 150.70.84.151 IP at honeypot and found a rather different comment.

"The IP addresses 150.70.84.151 and 150.70.84.41 are commonly seen in my webserver logs whenever one of my customer (inclusive myself) are using TrendMicro Internet Security withe the Phishing Protection enabled.
In these cases a encoded request is sent to an akamai server (The html-header of the response says: TrendMicro Server). This akamai server then seems to initiate a replay of the request from the above mentioned IP addresses.
If the Phishing Protection is switched off, no more requests are generated.
In my particular case a Java applet does some data transport using the http protocol to my webserver and all the request are replayed, which first impacts my statistics and the commercial use of the service.

I turned off my trend micro page checking toolbar and the visits quit as suggested by dieter.  I thought this was strange as Trend micro has been discussed here in the past.

I just thought this an interesting find.
