Can You Give Us A List Of Directory Sites That We Should Avoid (Like Yelp)?

In episode 189 of Semantic Mastery's weekly Hump Day Hangouts, one participant asked for a list of directory sites that one should avoid, like Yelp.

The exact question was:

Hi Guys,

Than you VERY much as always for your help on these HumpDay events, it is greatly appreciated

You were kind enough to give us a heads-up on how bad Yelp is with their constant solicitations if you use them as a Directory profile for a client, so I have ruled out ever using them

Can you please give us a list of other Directory sites that may be bad to use for the same or for other reasons so we can avoid them?

Thanks,
Gordon
