When reviewing the links of bigger and older client competitors I often see hundreds and hundreds of DMOZ clones.
It doesn't seem to be hurting any of the sites I see that have these 'links'. These clones usually only reproduce the more central, non-geographic, older parts of DMOZ, so it's sort of an indication of the vintage of the domain involved.
The ones I see over and over have the DMOZ attribution immediately noticeable, the same directory structure and the same exact listings. There's no attempt at disguise and I imagine they are discounted and neither help nor harm.
Google themselves ran a DMOZ clone for many years so I seriously doubt they have a problem with a site that has these sort of IBLs.
