Imposters AHH! And "Gray Tiger"

So, as the title states, this post is about impostering. So I visited a friend's den and I saw this person, whose username was "Silver" I clicked on her. Then She went somewhere else, and I searched her to take a quick glance at her trade list. I typed in "Silver" and I got this "gray tiger." For a long time, even in 2012, I used to see this tiger. It represented those jammers who weren't online for more than 30 days. I knew something was fishy. I typed up silver again and again. I then had a feeling that something was being impostered. I searched up Silver, but I changed the "l" to a capital "I". Then She appeared. Almost all impostering happens with the "l" and "I" confusion :P

Kay, back to "Gray Tiger". So when you type in the letter "a", or any word like "hi", you get this gray tiger. It's very weird. The weird thing is that you dunno whether he/she is a player or not, and the den, buddy, achievements, etc icons are "grayed out". I deleted a friend who never came online, and I couldn't add her back. Her "icons" were all grayed out!!! What could this mean.....? My best friend was not online for a billion days (not really((exaggeration))) and he was still normal...not even Grayed out. Does this mean that the person quit? Comment on what you think!!

And by the way here are some pictures of what I mean...
