Best thing to do is send an in game feedback request, and if possible report at least one of them stating they are botting and where. It does suck, I was in Deshaan earlier and there were about 10 bots running around in a line zerging mobs near the silent mire, it makes me so mad because it takes away the challenge of the game when they are just one shotting all the enemies when you are fighting them. Anyway yeah I am not sure if posting on the forums if GMs or devs will pay any attention, I always put it in a feedback request and report at least one, if not more of them.

Reported with screenshot and description as I always do. I just was so overwhelmed by the shear amount of them and the first time I noticed the speedhack that I just couldn't resist making a post on the forums about it.

If this speedhack becomes widespread and used in Cyrodiil it would ruin a big part of the game for the rest of us.

Bots I am used to, always report them, but never seen so many so fast and with such a hack before.

I believe a solution to this specific problem, for solo dungeons at least, would be to instance them. It is your dungeon, this doesn't mean you have to solo it, you can invite other players to it, but it still your dungeon, even if I did the dungeon already, if you invite me I go in to your copy of the dungeon not in to mine.

This solution doesn't get rid of the bots, but it would be great to let you do your thing, without having to suffer the bots.

Yeah I noticed the speed hack a few minutes ago on bleakrock isle. But unfortunately I've noticed in other games when there's mods and moding there is excessive exploits and automation in the player or automatons.
