Well, I was referring mainly to story and character spoilers. I don't really consider seeing the new Enterprise or the new TARDIS before the show begins as a 'spoiler.' I like to see the new Enterprise or TARDIS ASAP, too.
And that's the problem right there, everyone has a different defintion of what a Spoiler is.
The makers of DW don't consider revealing that Episode 13 is
set in an alternate universe where the Roman Empire still exists and is led by Winston Churchill who is still alive thanks to Silurian science and which also features Cybusmen and Cybermen
River Song is really River Pond
