That's a very good question Jiskefet.
Once a layout leaves your hand as a gift to another person, you really have no control over what they do with it. If it turns up as say a header for their own personal webpage, technically they should list the designers credits. But if they're not familiar with Digi Scrapping and the rules of it - they would quite innocently not know to do this. Could YOU be held responsible for that?? I don't think so. If they just post it on their site to show it off, while credit would be nice, again, only a digi scrapper would know this.
Of course these are MY opinions, so let's see what another designer has to say about this.
