Is ethn.io Safe?

I read their home page and still don't know what they do, except it appears that they track users activities on a web site to see how it is being used. But what this has to do with finding people that you would not ordinarily be able to find, or any of the other malarkey they talk about, I have no idea. The fact is, I don't want them tracking my activities under any circumstances for any reason, even if it is to "help" me.

Review of Pianosa's comment from ***** - 1. There is truth in asserting that ***** reports that they found no significant issues in their tests; BUT, what were their tests? Usually, Siteadvisor lists the files it downloads and tests, with result for each file. In today's report, there are no files,and no results. Every category of test that siteadvisor lists as its product is BLANK, which indicates that there is nothing examined by Siteadvisor. to support the robotic judgment.under any of the categories that Siteadvisor 2. Google SafeBrowsing is equally devoid of data and even worse, it states that it HAS NOT TESTED ETHN.IO at any time in the past 90 days - and yet, Google alleges with NO BASIS whatever on ethn.io, that, "...this site has not hosted malicious software over the past 90 days." I would say that Pianosa's review, even though redundant with respect to Google, is a low-confidence assessment, and similarly low is confidence in Google SafeBrowsing and McAfee SiteAdvisor with regard to website ethn.io.
