If you know about Flickr then you'll know that there are lots of people using it to promote their work: either blatant promotion or a little more cautiously.
Because you often see people being quite (or even very) blatant it's easy to be tempted to start doing the same thing: but doing so puts your account at risk of deletion without notice.
Because the guidelines are quite ambiguous I started a thread in the help forums. It's way to long to sit and read through, but there were some very interesting and definitive answers provided by Flickr staff fairly early on in the thread which can help you not inadvertently step over the line, and then later suffer the "This person is no longer active on Flickr" horrors when you try to login.
Here's a link to the thread.
