I support the indefinite block of Saladin1970. He has made no useful edits, and has committed copyvios, violated NOR, violated the 3RR, and has shown a significantly biased editing pattern. This much is, as far as I can tell, undisputed by anyone except the blocked user himself.
When you say "no useful edits," does that mean that you are "able to provide evidence of your accusations?" It seems to be that Saladin1970 definitely has made useful contribution(s):
http://en.wikipedia.org/w/index.php?title=Turkic_peoples&diff=53825534&a...
It's a shame it was reverted, http://en.wikipedia.org/w/index.php?title=Turkic_peoples&diff=53987242&a....
And then there is also:
http://en.wikipedia.org/w/index.php?title=Spanish_Inquisition&diff=prev&...
Which may not in and of itself be useful, but certainly contain enough raw data to turn it into something useful. So it is NOT undisputed that Saladin1970 has made no useful contributions. You simply don't treat editors that tries to be useful to the project in the way Saladin1970 has been treated.
