It's worse than just the same alias. Apparently "Nicholovich Rose" underwent a sex-change operation (or just likes the feel of silk on his thighs) and became just "Rose".

Here are both posts in their entirety; see if you spot a pattern or two.

The newest one, from "Rose":

the most helpful teacher agent in Shanghai
By:Rose <rose_aaa@aol.com>
Date: 10 May 2008

I am a native English teacher from the U.S.A.
I have been teaching in China for 4 years. In the spring of 2004, I found employment in Harbin. Unfortunately, the conditions of the job were difficult and the housing was not acceptable.
I was introduced to Mr. Frank Zhang by another teacher. After I contacted Mr. Frank Zhang, he very kindly and quickly found me another job. Subsequently, I relocated to the school arranged by him. I was very happy with everything at the other school.
After I finished my contract, Mr. Frank Zhang secured me a position in 2005 on the completion of which I returned to my hometown of Houston, Texas.
I returned to Shanghai, China and met with Mr. Frank Zhang in September, 2006. Again, he quickly found me a job in Nanjing, the capital of Jiang-su province. I signed a 6 month contract with Nanjing College of Technology. Following that contract I moved to Beijing and did some private business.
Mr. Frank Zhang has a great reputation throughout China, as a kind, honest, efficient and helpful recruiting agent. I am greatly indebted to him for all the efforts he has made on my behalf. I also know many other teachers who seek Mr. Frank Zhangs assistance in finding jobs year on year.
Now, I am teaching in Suzhou University. This position was also arranged by Mr. Frank Zhang. I want to take this opportunity to thank Frank Zhang again.
My sincere thanks to you, Frank. Keep doing a great job.
I whole-heartedly recommend Mr. Frank Zhang to people seeking suitable, high quality, good value and enjoyable work in China. He invariably gives excellent advice. Should you have any doubts about an intended position, Mr. Frank Zhang will arrange for the school to contact you directly.
Furthermore, I have told many colleagues and friends about Frank Zhang's useful help. I would like to express my deep appreciation and say "thanks" to Frank Zhang once again.

I am a native English teacher form US of American. I have been teaching in China for 4 years. in the spring of 2004, i got a job in Harbin. but the job was not good. they did not give me a good house. Some other teacher introduced Frank Zhang to me. I contacted Mr. Frank Zhang and he was very nice to help me at once. So I moved to another school that was arranged by him. I was very happy with everything in the other school.

After i finished my contract, Mr Frank Zhang gave me a job in Hunan in 2005. And then I moved back to my hometown, Houston.

I came back to Shanghai, China and met Mr. Frank Zhang in Sep,2006. He helped me again get a job in Nanjing, the capital of Jiangsu province. I signed a 6 month contract with Nanjing College of Technology. Then I moved to Beijing and did some private business.

Mr. Fank Zhang is one of most famous and helpful agents in China. I was too much moved by all that he has done for me. I also know many other teachers always ask him for jobs year by year.

Now, I am teaching in Suzhou University. The job is also introduced by Mr. Frank Zhang. I want to thank Frank zhang here again. thanks, Frank. keep doing your good job, don't care for those disappointing people that you refered. Good people will only trust the facts. They don't know you at all. If anybody wants to get a good job that is suitable for youself, You can contact Mr. Frank Zhang. He can give you some good advice. if you have any doubts, Mr. Frank Zhang can make the school contact you diretly. So no tricks, no games, no jokes at all. all the words of those badmen are obvious lies. Anyhow, i have told most of my friends about Frank Zhang's useful help. I want to say "thanks" to Frank Zhang again and again. I don't want to be attacked here after I give out my reviews, I hope those people not to attack me.

Frank thinks we're stupid. Sadly, I guess enough of us really ARE stupid to keep him in the recruiting business.
