Spoon's [almost definitely] fine. Foil can do it though, especially crinkled up like that.

Could be, but the mailbox is from a company in Mississippi, and it has a flag on the side, which I've been lead to believe is an American thing.

The letter also has a standard prepaid postage mark used in the USA (though I don't know how that works in other countries)

It's most likely not OPs and is just a repost.

Also a premium subscriber, and I it's definitely worth it to me (especially since it comes with music and I've got the grandfathered price)

The biggest problem I have with it isn't even a problem with premium. It's that it doesn't deal with sponsor spots in videos.
