It concerns me greatly that Commons seems unable to deal with a user who, at various times, has attacked a Jew with anti-semitic cartoons, has thrown racist abuse at a German theen harassed that user - and still has numbers of admins willing to unblock him, simply because he does supposedly good work on Deletion reviews. Diod I mention the Jew was blocked for several months for A SINGLE COMPLAINT ABOUT HIS BEHAVIOUR?
Pieter has harassed numerous users away from contributing to Wikipedia. That he is still editing after all he's done is disgraceful. Commons' administration has clearly failed, and failed horribly.
A list of evidence follows:
The most recent incident was racist abuse against a German user, followed by harassment http://commons.wikimedia.org/w/index.php?title=User_talk:Martin_H.&curid... http://commons.wikimedia.org/wiki/File_talk:Farrel.jpg and http://commons.wikimedia.org/wiki/File_talk:Tiotio.jpg
The report, which before I noticed and acted upon it was full of people claiming that racist abuse was fine, and that Pieter was being harassed by being called out on it, is here:

Pieter has a block log as long as your arm: http://commons.wikimedia.org/w/index.php?title=Special:Log&page=User%3AP...
However, he also has an unblock log, where the same few admins constantly unblock him, without insisting on a change in the problematic behaviour. This is a user who gets serial warnings and second chances, all the time becoming bolder and bolder.
A few past incidents will suffice:
The Wall of Shame incident, and the Havang_nl harassment.
Pieter's modus operandi has been to attempt to harass admins who do things he dislikes by scouring their image uploads to find something to request deletion on. The validity of these deletions varies in quality, and are often grasping at straws. Several of the blocks in the block log are for this.
One of the clearest incidents was when he attempted to refight old battles where the DR had gone against him, attacking the admins who uploaded and the admins who closed the DRs as keep. Here's the wall of shame he created.

The next few edits are him editwarring to keep the Wall of Shame up. He got blocked for this. He made an unblock, and Havang_nl denied it. So he promptly attacked Havang.

I believe there were other incidents involving antisemitic cartoons being used to attack Mbz1, a Jew, but one can be found here, where he constantly insists on including a cartoon which he knows will upset said Jew.

It's clear that Commons cannot handle him, and I beseech the Foundation to step in, investigate the matter, and deal with it. I also think that every administrator invoilved in defending him, and encouraging the harassment of other users, should lose their admin rights.
