I of course understand the historical context that lead to the fact that Germany has the most strict privacy laws in the world. A current example is the Google Streetmaps / wi-fi data collection scandal, that might affect Google's operations in Germany.

But I also have to say (and I know alot of partners agree on this) that your "concern" is becoming so big a problem you should consider moving your company to another country for the sake of your customers right to freedom of speech.

The way I see it Spreadshirt provides a publishing platform for its partners - its of course your obligation to make sure you're not getting sued for copyright infringement, but you also need to govern the freedom of speech.

If you go to spreadshirt.com you will find 1500 facebook related products - if you type in facebook on spreadshirt.net you will find 0. In fact try to type in any company name and the result will be 0. Not only do you reject designs from the Marketplace, you also edit search keywords to meet your "safety standards".

We as European Citizens also have the right to freedom of speech! I have the right to write "Facebook sucks" on a t-shirt and there's nothing Facebook can do about it.

Can I sell such a t-shirt and make profit of it? Well thats much more debatable, but for me its a decision to be made by the courts and I frankly find it appalling that you just choose to pre-censor because that's the easiest solution.

There's a fine line between censorship and causion - and you are being very cautious.

I think the current problems with partners is founded in your Germany-centric approach to copyright. An example is your guide for motives you cannot accept:

If you look under "Unconstitutional" you will find several political symbols and the text: "These designs break the law, some even break fundamental rights. No-go!". But wait a second - several of these motives are only unconstitutional in Germany, not in Europe, not in the rest of the world. Of course its fair that you don't want to print such stuff, but then you could at least be better at explaining that you operate out of Germany and therefore is bound by their laws. Afterall you operate in so many countries - you have local offices and so on. I cannot expect people to guess that you are bound by a specific very strict German regulation - you need to explain it to them :)
