I have a website with a guestbook. Entries have to be approved by me before they are published to my website.
Everyday for the past week I am getting guestbook entries that say this (for example):
Email address: (first name).(last name)@gmail.com
Display name: Something weird like QekifhZWopDSlxa (I made this one up)
Message: Good site, admin.
The IP addresses and email addresses are always different, but they always say "Good site, admin." and have the weird code for their display name. The IPs are located in Malaysia and Pakistan.
When I google the email addresses I see hundreds of the same messages on people's guestbooks. And they are all from this week.
What is the point of this spamming? They aren't linking to a website or displaying any ads, at least they can't on my website.
