The reason why you see all of the players suddenly storming toward one spot is that every server has multiple hunting Linkshells all inter-networked with each other. So if one player sees an elite mark, and calls it in shout, or to their LS, that gets sent to several other linkshells. That's also why these players are late to the kill so often.

I don't know about these 'other botting programs' but they are clearly giving them an advantage over everyone else.
