By doing this, Mr @berniesanders has achieved a couple of things. He's built himself a few quid which he uses for the greater good of the community, and he's used his bot army to give everyone who took the time to comment some free money and created himself some goodwill. This is more than many of us might earn in a day, and money that will not be available for the greedy whale fuckers to have in the future. Win-Win as far as I can see. Lets all just say thank you to him. Sometimes it really is that simple :-)
