Thanks Evan,
while I perfectly understand your point in sharing that link with me that's not an applicable option: I am evaluating a code review solution and I initially fall in love with Phabricator, so much I've started a large scale PoC, which is where I currently am.
Sadly, either I failed to understand the real capabilities of this suite, or the suite is not fit for our needs. In any case, I don't have a budget for this PoC other than my team time, meaning I cannot take your suggestion into consideration and I also don't think it would be practical as part of a PoC.

I don't know if this is still being worked, but I find myself in a tough situation: I have a team member which has 1k+ audits, but he has recently resigned and I don't see an easy way to remove that person from each and every audit he has been assigned to!

It worked for me too, the trouble in my case was created by the character § used in a filename pushed into mercurial from a Windows client.
