Update (08th April 2011)
Just out of curiosity, X-Companion is still on line and in duty.
If you compare the whois data of zuzana.com and x-companion.com it should be clear that both sites are from the same owner:

Even the phone contact number on x-companions site is the same as formerly zuzanas.
The question now is, why has police shut down zuzana.com but not x-companion?
