I don't watch Bachelor Pad. It looks too sleazy to me. It airs during the off-season, when The Bachelor(ette) isn't on.
Spoilers are any info from other sources about the show that spoils events in future, upcoming shows for everyone. For example: naming the final four guys picked, naming who Emily ends up with. Plot points that haven't aired in the show yet or in the previews. If you happen to see Emily driving driving around town in the next few weeks, having a hidden tryst with the guy she picked, refrain from telling us about it. But, after she's made her final pick, post away any info you get!
Spoilers can be found pretty much anywhere. Just do a search for Emily/The Bachelorette, and you will EASILY find some source, tabloid website, article, or magazine that will give you a spoiler on "leaked" upcoming events. Sometimes in just doing a Google search, you may accidentally get spoiled from the titles listed in the search, without even reading the whole article.
The threads here on the DIS for The Bachelor(ette,) have been traditionally NON-spoiler threads. (Each show here has their own rules & personality.) It should be a SAFE space where we can come and discuss the show without people telling us about OTHER stuff they've read, even if we are speculating about it. The point for us here is to have FUN speculating on what may happen and to be able to discuss it all with each other.
There are plenty of other threads/websites where people can discuss spoilers. As I mentioned, there is usually another thread started here, it never takes off. Whether because of the OP, or no one is interested in it, I don't know. I don't participate in that thread, as most others do not seem to either.
