Not sure if we are talking about different spammers here Bots or humans

Would spammers (the human ones) use a permission request function for spamming?
I guess the answer is: if the function is there they will use it.
From my naive understanding (based on what authors have said in podcasts/youtube etc.) the reason they ignore the inbox is that the content is '97%' of non-constructive feedback, "MAKE this or that for me!", repeating questions that have already been answered on the description page.
The more popular the mod is the worse it gets. I do not know about bots and unwanted marketing type spam.
It may go against Nexus's philosophy, but maybe such a function should be available for premium members only
