In an effort to maintain a thorough encyclopedia of Titans, we like to detail everything we can. Any details related to plot or character are deemed as spoilers.
Hoping to provide up-to-date information, spoilers from an episode that has just aired are considered free range, as the episode is open to the public to watch. Directly following an episode's airing, any and all spoilers from it can be found anywhere on the wiki.
In an effort to maintain as coherent an encyclopedia as possible, there needs to be a line at which we draw how much information is included on the wiki. When an episode has not aired, details from it are often scarce, and far and few between. While these should still be sourced properly, they should remain only on "production pages" (ie. out-of-universe pages such as episodes, actors, crew and TV series).
Under no circumstances should spoilers be added from an episode that is in the middle of airing. Episodes often build things up in a very specific way, such as revealing half a piece of information to later reveal that it was in fact a misdirection. This can lead to errors in pieces of information and incorrect information floating around, that can often then find its way on to other pages, ruining consistency all round.
