How do you deal with constant undercutting?

[Nixxe]

I'd wager at least a few of the constant, instant undercutters are botters. If you're always getting undercut instantly by the same people what are the actual chances that they're always on at the same time as you and always able to undercut right away? It's like when I tried to give the benefit of the doubt to gathering botters, that we just had the same play schedule and goals. There's almost zero chance that they'd always be at the node at the same time as me, playing at the exact same times.

I'm not saying there are no botters, but in my many years of playing MMORPGs and other online games, it has become clear to me that people frequently rush to the bot explanation over every little action that doesn't fit into their narrow idea of how people play the game. For instance, how do you know you're getting undercut every five minutes unless you're checking the MB that frequently? And if you're checking it that frequently, why is it so unreasonable for them to do the same that they must be botting?
