Once again, as described at Blogbar, there are content thieves around. Here's a preventive explanation of what a CC license with Share-Alike condition and Non-Commercial means: no ads on the pages. No commercial site - for example, paid accounts or similar. And yes, I mean Non-Commercial seriously. Share-Alike also has a simple explanation: a site that reproduces my content must be under the same license as my site.
Those who cannot meet the two conditions (we won't talk about the explanation of Attribution) will have to ask. And this does not mean that a lack of response is a silent consent - those who do not have explicit permission from me and cannot comply with the CC license must keep their hands off my content.
And those who think I can't do anything to them: those who are stupid enough to automatically pull content from RSS feeds should consider that the pulling machine is recognizable (especially for "stationary" services) - and that appropriate feeds can be provided for individual servers if you program your software like I do. And believe me, dear content thieves: the content you would then pull would definitely not please you.
