Pretty much the same as already said. I do try to be polite to people. I don't overfarm an area if a lot of others are around. I three box only, so if a person is nice enough I'll let them join up to get a quest done that I'm also doing.

I tell them I'm multi-boxing and point them to this site.

Sometimes players will just follow me around for a while and never say anything. Just curious I guess or trying to figure out if I'm botting. I'm sure I've been reported but never approached by a GM in the 1 year 3 months that I've done this.

Had one fellow this weekend follow my priest and two warlocks around, asked what I was doing. I told him "multiboxing" and referenced this site. He followed for a while then made a snide comment about my two 31 level warlocks having the same exact gear and that I must have too much time on my hands. The comments made no sense. I just said "thanks" and went on my way. He left.

I haven't had many threaten to report me. I did once when I had 3 undead mages named Orange, Apple and Cherry. Guess they didn't find that humorous.
