Yeah, there's a lot of drama with Dream, especially. He's been accused of cheating the manhunts and them being staged, cheating in speedruns, etc. I have no idea about any other drama or 'actions' that could lead to someone not wanting you to interact with them.
The person said its fine if you enjoy the content, but do not interact if you support their actions. Im so confused lmao. As I said I dont watch them religiously so I have no idea about the drama going on with them
There is a lot of drama within that group, but I do not keep up with a lot of it :/ There can be a plethora of reasons why people say not to interact with them because of the team's actions. I really couldn't tell you.
