I'm told, that doing the same thing again and again, and expecting different results, is the very definition of insanity.
So to keep copy/pasting the same thing into multiple group chats, again and again, day after day, week after week...
If it were ever going to work, it would have worked by now and you would be up to your armpits in Dom/mes/subs/cash. The fact that you aren't is proof that your advert doesn't work. And now after having seen it 30 times, it also proves that you are unoriginal, lack imagination, lazy, and not very smart.
You are also being annoying.
