Not suggesting heavy research but if a certain user is definitely the one who made the alt especially for sig spam... are there any repercussions? Sigban, temp-ban?
I understand it would be hard to prove ...
as you said, it is pretty hard to prove. what indicators are used to prove it?
even if they have same IP, that's not enough proof to say the accounts are owned by one person
It's not low effort spam I was talking about, but mainly pretty well constructed replies to idiotic questions.
to mitigate the issue, you can report the thread and ask mod to lock it,
but mod needs to post reply and put a link to a good thread for a solution
without it they will just start another thread asking why the old thread was locked
