If it is a question then you're expecting an answer. Correct ?

So here is your answer : this happens because they don't give a crap / bother. Simple as that. If you don't mind either as you claim, toggle off and that's it.

What people are pointing out is : the issue that make you raise this question seems to be boss beyblading. If you see it as a problem, and toggling off is a quick solution, why not apply it ? Cause this 3 page topic won't, alas, magically make them toggle off. Since even telling them directly in game in chat doesn't seem to have an effect...
Is it your fault ? Absolutely not. Can you do something about it ? Absolutely Yes. Up to you then.
