About 2 or 3 weeks ago, (after the last reboot or prior to that it hink) I have PM'ed Samuel on forum telling him red foxes are made Living again, so they are Tamable. I got no answer and assumed he prefers them to be harder to kill.
Still I have never used them in PVP because I thought they are OP in PVP and thought maybe it's wrong to be able to use them in PVP.
Since GM just said on this thread that foxes should not be tamed I will stop doing this. In case of bugs, first you need to report and ask if indeed is a bug, then the confirmation should come from the GM and the player should stop. If the player doesn't stop after the warning, then yeah it is a bug exploit.
We can't know what exactly is a bug or not until GM confirms.
