I like the idea of disabling the link, since we really don't want to direct people to their site, except maybe to write angry letters.
I think we'll definitely remove the links.
Some bootlegs are compilations and not reprints, and those ones would be "standalone" albums in the database. I can see your point on the use of the R symbol for reprint, however (colorblindness aside) the red text should be enough to alert the viewer that this isn't a true reprint. I think the notes field can be used to indicate the sources for multi-source bootlegs.
BTW, we've only added a few, and mostly those were either ones that were submitted by non-staff by mistake, or ones where I noticed that bootleg scans were uploaded to the official album, so I created the bootleg and moved the scans.
