On yahoo 360 can you have advertisment banners?

Here is what is in the TOS about this, labeled G: upload, post, email, transmit or otherwise make available any unsolicited or unauthorized advertising, promotional materials, "junk mail," "spam," "chain letters," "pyramid schemes," or any other form of solicitation, except in those areas (such as shopping) that are designated for such purpose (please read our complete Spam Policy);

Go there to click on the link for Spam Policy. Other people have posted that you may not do this kind of thing on 360. Although I have not seen anything that says you can't, it's probably better to not do it. What you can do-is set up a seperate page (with geocities or whatever) and link to that in your blog.

It is not allowed
