Thanks, Mr. (I evidently deleted my question close to the moment you replied.) But I appreciate knowing your insights on Soulseek... I'm still new to all this.
I retracted my question because I later found something in the configuration of my Soulseek client that might explain why I was getting rejections: there's a checkbox for displaying "privately-shared" files in search results.
So I may have been clicking on a user's private files, that would then come up as
Denied. I un-checked that box and, so far, have not experienced it again. </sheepish>
