Crowds of people will feed off of each other. If a person or group starts to hassle you for being a "botter" or "farmer" or "no life hacker" then other people who wander by will automatically join in. The larger the group the easier it is for people to join in with them.

At the same time, others will watch silently and might be pretty intrigued at the fact that despite the abuse and reports, you're still around. They may find out more about you and/or multiboxing and develop a much different opinion than that of the average ignoramus.

So hang in there, the people who will learn to understand your side of it and support you are the sort of people that it is worthwhile to impress. No one wants to impress some mindless idiot who jumps in with the crowd and tries to argue that the fact that you have more money is something to be ashamed of.

As for me, I do as others have said- I avoid being seen as much as I can, I'm not interested in being noticed. I just want to level my toons and see how far I can get with them. I typically ignore the idiots and will reply to people who are supportive or genuinely curious. That way I avoid the stress of wanting to club some moron to death with his own arm.
