Spotlight can't find kMDItemKind=="Alias" ??

Question

I backed up a bunch of old user accounts from a machine. When you create a user account, one of the folders created is "iChat Icons" within the Pictures folder. Of course, the iChat Icons "folder" is actually an alias.
I am now trying to run a script that has to follow aliases on these folders. However, having it loop through thousands of "iChat Icons" folders is taking forever.
I thought I could just do a smart folder for "iChat Icons" but that doesn't work. A similar search for a kind of "Alias" doesn't pull them up either.
mdfind kMDItemKind=="Alias" finds some aliases scattered around the hard drive, but no where near all of them. If I search for a picture sitting next to the "iChat Icons" alias, it comes up, so the folder appears to be indexed.
Any suggestions? I sure don't want to go through this manually...

Mike -
At one point in time, I was using the computer as a file share, and I wanted each user to have their own log in. It was a hacky set up, but it worked.
When we moved to an actual server, I copied all of the user accounts over to a new machine using Target Disk Mode, and reset all of the permissions. I have yet to go through each folder and copy over each users files to the new location.
So, now I have a ton of user accounts that have all sorts of data I don't care about (like the entire Library folder). I was hoping to just use Spotlight to search for things and delete them in batch (i.e. Kind: Folder, Name: Library). For most of the things that worked fine.
When I attempted to FTP these accounts to a new location, the ftp program is trying to follow any symlinks/Aliases. So, I wanted to find those aliases (the iChat Icons are the only ones I know of so far) and remove them. I thought I could just search for them, but a search for both "iChat Icons" and "Kind: Alias" turns up nothing in those folders.
These aliases were made automatically, although my current machine doesn't have it and it may have only been around in Panther.
In the end, I wrote a PHP script to go through and remove the Aliases, so it seems to be taken care of (assuming no more pop up). I just thought it was odd that Spotlight only seemed to find some aliases.
