well, it's not that i support the idea of telling
spoilers without a previous warning, but the
question should be how much time should be correct
to wait before talking about these "spoilers"
without warning. FY has been already released in
the US for quite a while and for sure there are
and there will always be people who have not
watched it.

In my opinion when a series has been released for
at least 1-2 years comments about it's plot
shouldn't be considered spoilers as people has
been given enough time to watch it.

Refering to the original post, the guy is trying
to sell a cel, so it's quite logic that he
describes it that way (even in this forum, and
please take note that i'm not defending it). There
are cels from many series like the one in question
that are spoilers by themselves.

So the question should be as i said, how much time
do you consider is enough to wait before talking
about a series plot without considering it an spoiler.
