@Jayde: It's an audio drama about an alien lifeform that delivers pseudo-immortality to Earth. Other factions want their hands on the tech as well so there's a conflict.
It went on hiatus for a very long time because the producer had severe personal issues so he was dealing with his family at the time. I would say it's been at least eight years since I listened to the drama because I remember being introduced to it in 2011.
They dropped season 3, the final season, this week Monday as of this writing.
The character that @19 spoiled is significant to the story now that I've started listening to season 1 again. So if you do end up listening to it, be aware that you won't be able to connect with one of the main characters because you know his ending already.
On mainstream forums, spoilers are immediate grounds for permabans so @19 got off easy on this one. I remember when Game of Thrones was still running, even the actors were under contract to not reveal anything even hinting at a spoiler or they'd be fined. I'm one of those that absolutely hates! spoilers, because as @Jayde pointed out it kills the mood in many cases. I never watched Game of Thrones but I knew a lot of people who did, and the reactions when someone would spoil something were cultish.
For those of you who don't think this is a big deal, maybe you simply haven't waited as long as others of us have for the final season.
@Simba: I love the passive aggressiveness there with the common sense comment. (Sarcasm.) Apparently you don't know what a spoiler is or you simply don't have enough common sense yourself to think "hey, even though I've finished it because I have all the time in the world to just sit there and binge the damn thing, other people don't." I've been looking forward to starting the series this weekend after work and you pretty much ruined that whole experience. Consider yourself lucky to not be on a forum where they take spoilers seriously or they'd never let you back on.
In case you don't know, it's common sense (your words) and considered common forum etiquette to not spoil a series. Just take @34's example where they clearly warned of a spoiler ahead.
If it was up to me you'd be permabanned like I've seen other forums do when someone spoils something. In fact I daresay just getting a warning is letting you off too easy. It's akin to mentioning a significant plot twist to Harry Potter's character Dumbledore that happens in The Half-Blood Prince.
