i myself am on a server that doesnt really like multiboxers.
Ii have many more fans cheering me on, i mostly see "lol wtf haxx" or "Meeo is a fat bastard and has no life" or etc etc the list goes on.

Personally i make friends with the ones who are more interested and ignore the ones who talk crap. i aim to be an ally and and enemy. Multiboxing is your time and money, not anyone elses, dont let that affect your judgement in what 'you' want to play. Just be prepared to talk with a GM in the future at least once, they will verify all your accounts have the same billing and name, and then they will let you be on your way.
