Well I used to agree with what you said until I realized spammers can't start to chip away at your brand and image on Twitter. One new tactic they've just started is using @replies to show up in your stream. Just recently I've had a sex toy company and a female escort service @ reply using my handle. While everyone knows I am not a sexual deviant (at least I hope they know that.), I don't think this is good for anyone's personal or company brand. One way I have found to combat this is by just blocking the persons account. Then the @ reply disappears. But once spammers figure this one and out these types of @ replies become rampant, how long will I have to spend blocking these people?
Stop taking this so seriously! Its a damn twitter account. Who cares what people close articles with. The more people that follow them the happier they are. To each their own.
I don't care if they have free will or not. I just ordered a bunch of fruit fly killer traps a store just 2 hours ago. I can't stand fruit flies and I'm not sure who can. You should kill all fruit flies as well. http://www.fruitflysolutions.com
I don't know if anyone is copying anyone here. Its possible the engines are being licensed from a third party company which would explain the similar look.
