I should start with "I get it". A bunch of sales people types on quotas or cold call mavins, can't rely of lists, etc. so they have to get "creative" about how to get to me. Or customers. Having said that, this just highlights the work that needs to get done in order to close these types of 'loopholes' and so-called creative ways to get at my email address. This just isn't good (nor any of the aps doing the same thing). In taking a look, using a stale LinkedIn account from a testing service got me in to take a peek. Didn't find my email address.
I tried to find my own email. It can't find it.
The logged in option is to first link your Linkedin Account and there's no other info about the service in the landing page
My first impression is that it's a lead generation webpage to get your Linkedin Profile. (Which it does)
I'm not sure about the Privacy Policy (there's no link for it in their website) since I already removed my Linkedin profile connection to E.E so probably my email address/name/photo is still on their database.
I think it's a great product and there's definitely a need for it — but I think for now I'll stick to using other email finders.
