I was recently migrating an old blog to community server through the web services API. For some reasons while migrating over the posts, it would die after the 36th item every time while giving a generic "The post could not be added" error. I thought that it could be something to do with that specific post, so I removed it from the list to migrate. Same error. So I began to wonder if it was some spam post count limiter, and there was no blog posting limiter. Needless to say, I was pretty confused....
