I don't see any explicit policy on seeding "adjusted" recordings. Most of what people call remastered really isn't, if you know what I mean. I am not very keen to download a CoolEditPro-ified version of a show, no matter how good someone's intentions are. My personal feeling is that:

...if you don't own/transfer the master source, only very limited modifications are acceptable:
-speed/pitch correction
-maybe gain adjustment assuming original recording is not clipped
-maybe balance adjustment
-dc offset correction (hi Rider!)

ie No EQ, no NR. Just don't do it.
