I think this is a dangerous game to play if you want to keep your link directory.
I don't care about the site, I just have it hanging around. Someone else built the directory back in the day and made all the money off of submissions. I bought it (as the feeder for the DP network if you must know :) ) and never added any links or took any money. And the site's just sitting there, defunct. 40000 pages of static HTML and I'm not even kidding, I have to edit everything by hand and the page names are not intuitive.
And if it was a business model (which it's not), then a google penalty on the site would be fantastic. More people wanting to get delisted.
Realistically, the people asking for link removal are panicking. The site's not great, but it's not that bad either. The directory was actually quality back in the day, custom screenshot, well organized, good descriptions, custom layout. At worst I'd say it's a mediocre backlink. It's certainly not a complete spam link.
