thanks for the information. Yes, today I read the text independently, because a friend of mine (the German lawyer) has become an active member of the Karl May forum to find other customers of Uthe, who are interested to sue him.
The overall information is that many people over 30 years now tried to stop Uthe's activities, however with only little success. This is partly due to the German laws and partly due to missing civil courage. Here and then he is brought to psychiatry but sent home after a few weeks (there are many more serious cases that need to be taken care of). One commercial collector argues that we should just pity Uthe, because he is in a similar situation as was Karl May then. He also thinks that any official accuse is not worth the time. However, my friend will continue and hopes to find other betrayed customers.
