When I tried to report the misconduct, I was arrested 2x at a German psychology conference ( @dgps.bsky.social ) after false info was given to the police in NRW (where my ex-wife works). This investigation has luckily recently been dismissed (meaning wrongful detention!).

I had to pay over 15,000 euros despite:
(a) I barely earn anymore and hardly survive financially
(b) My daughter lived with me for parts of that time.
Still, money was taken.
