I already see some spam links in there. A webpage containing an image and email address is not a legit service.
Also, it would be nice if you could have a link in each category listing to add a new listing to that category. That will grow important as the site grows and people forget what category they were interested in.
If you think it's a spam, you can report / rate it. That's why it's an open directory. Also i'm trying to be careful with removing links / email addresses in details. Would you kindly give me an example for scam lookalike listings? That will teach me.
About link for each category; i'm going to investigate and look what can be done with the infrastructure i use.
Thanks for your feedback.
