"The more the merrier" as far as I am concerned... I've taken to flagging some of the worst offenders I encounter. I fear we're only on the very leading edge of a massive influx of such users... and *"but we're on the blockchain"* notwithstanding... these "clicking for cash cockroaches" can take down a site in a matter of months. 

Right now, we're only dealing with 2000-odd new accounts a day... try dealing with two *million* accounts in the course of a few months. 

So good luck to you, whoever "you" are!
