Is writing in German seen as spam?

The title says it.
I wanted to try out this microblog, thought I signed in an wrote some text (in German), it was classified as spam, wrote some more etc.

The other problem is, that I seem not to be able to login - I sign up as I did here, but the system says I’m not and there is no support for anonymous posts.

Thanks for your help!

We don’t flag any particular language as spam automatically – usually these kinds of accidental flags are due to excessive links or HTML.

Can you share what your username is, either here or in a private message? Then I can take a look at what might be going on.
