I reckon this is as much of a 'fuck you with your plots, theories, plastering social media with your 'OMGZ I saw Jon Snow on set!!' bollocks. Here's a spoiler image' by HBO more than anything else! I can see why they've done it! But personally, I wish they wouldn't have done it. Let's just find out the normal, boring way - by waiting a few more months!
Drives me up the bloody wall - some things are simply not avoidable. Same as Dr Who on Saturday. I didn't get to see it until last night, kept away from the usual sources (including the Dr Who thread on here) but there was a headline in a local newspaper of all places which immediately told me what had happened (not directly, but it took me less than a second to get what they were alluding to). And I knew that was going to happen purely because of the spoilers that have been constantly posted for the last few months.
I think it's a different thing to discussing and speculating - when people use set locations, leaked scripts etc, I find it really frustrating. And then when the things make it onto air, it's harder than ever to avoid.
People are far too impatient these days.
