No, I did not test it, I didn't test Xolox either, yet I'm blocking it, - just because I don't want the type of people who use Xolox (Gnucleus, Morpheus, GTK-Gnutella,...) to download from me (of course I blocked them one way only, so my download-experience remained optimal).

Being xenophobic is completely legitimate on the internet, all I do is making use of my basic freedoms.
