In general bad faith means that someone is lying to you, either implicitly or explicitly, when engaging you. An example of this might be to act interested in a point, request sources to back it up, but with the intention to never look at the sources. Instead, the intent is to attack them for not providing sources making them look like their opinion is unsourced if they don't provide any, attack the sources if they provide anything that might be considered controversial, or to ignore them entirely and move onto the next person if they do provide good sources. The goal is to at worst waste their time and at best make them look like their position is unfounded. Other examples might be asking questions when discussing a slightly controversial topic to get even more controversial replies that you will then quote mine to attack the poster, even if the quotes weren't controversial in context. A less agreed upon example might be someone who is purposefully being misleading because they don't want to expose their true goal, but whose true goal is to educate the person. Asking leading questions to get someone to reach a conclusion when you would not be able to argue directly for that conclusion. This last example might even pass as an acceptable form of bad faith dialog because it is done with the intention of having a good faith conversation on a topic where good faith conversations aren't possible.
