I believe the checkuser system is significantly vulnerable to abuse, and am happy to explain my concerns in greater detail elsewhere.
I think both Lar and Slimvirgin have been let down here by a systemic dysfunction, and I also believe that gaps in the checks and balances of the checkuser process may have lead to its abuse. I've been asking a few questions here and there about this for a little while, and would likely 'plug in' to an on-wiki process of some sort examing these issues in general terms.. it's quite hard to get straight answers from some stakeholders!
I'd like to formally request here that a checkuser notify me as to when checkuser was used on my current accout, User:Privatemusings, and also on my previous accounts User:Purples, and User:Petesmiles.
I support Slim in her right to access this information, and ask questions concerning the propriety or otherwise of any checks run - ironically I suspect Lar might too - the guidance to checkusers seems to have been far from clear on whether or not such information can be released however.
I asked David Gerard about this here too; http://en.wikipedia.org/w/index.php?title=User_talk:David_Gerard&oldid=2...
cheers,
Peter PM.
.... and could I come off moderation please? - I believe that process may have been misued in my case also.. happy to talk about that too! - and just because I'm paranoid... right? :-)
