Its quite interesting, I had a chat with the new super SEO guy yesterday (he is a very nice guy) he said he is not an SEO professional but a software developer who dabbles in SEO.... anyway, he has written a script for the client that submits his website to search engine everyday (or something like that). I wish both the new SEO guy and the client all the best.
Seems like a blackhat method to me. The client's site may get banned because of this or may get penalized heavily because of using such SEO techniques.
This is why most SEO prefers to work alone, you cannot work with another SEO whose methods are different from yours, you will end up having discussions you should not be having about what is right and what is wrong, plus one's work is bound to interfere with the other's work.
Actually, it's fine if both think in the same manner, and have equal depth in the subject..actually its an art, people have different approaches towards the same thing.
