Is there a significance behind the domain extension? Specifically, the ".fail" domain extension. Something about going to a site where the extension literally says "fail" rubs me the wrong way, but I wasn't sure if I was being paranoid. I'm (obviously) new to this.
Also, second question, what do the "caution" signs next to the mirrors on some markets' page mean? My bad if the answer to this is listed somewhere.
Caution signs just mean it's an external link so people know that they are clicking something behind url tags. The .fail domain is nothing to worry about. It's been used for years by various services and doesn't mean anything. It's kinda funny like calling an letter from LE about a pack getting seized a 'love letter'.
