I do believe that its bad that the streamer did badmouth that person but until recently SE never took any outside information to punish people and I am not sure if I like that they suddenly are allowed to do that. Especially if they still turn a blind eye to famous raiders that are using parsers for their raids.

So if they do suddenly take outside information than be clear about this and fair. First tell us about this so that people can take actions (like not showing their streams with parsers) but also that everyone needs to "fear" this and not turn a blind eye on certain cases.
