I have seen, so far, comment spam trying to promote a certain private college in Singapore.
The author is always entitled "Degree Singapore", and the URL it points to is the website of the college and a Hotmail email address with the college's name on it.
The comments are along the lines of "bloggers have made things real easy" and "blogs have become avery common and low cost form of marketing online. Good for Bussinesses!"
The spam is also occurring in sites like ShaunChng.com, ID@NUS, and Sandeep's blog.
Raƒƒles Educ@tion C0rp C0llege, care to explain?
