Couple of things to consider, folks. Disclaimer- I'm not a fanboi or a hater, just a player.
First, you have to be very careful of sites advertising hacks, many times it's just a way to get a Trojan on your computer. I've only found one video advertising actual hacks, and it smells like a forgery to me.
First, speedhacking. So far I haven't seen any proof of an actual hack or exploit. There's one youtube video from a popular bot-maker advertising the 'hack', but from what I can see in the video there isn't any 'smoking gun'. You can't see any other characters or npc's walking around, or objects with motion animation, so there's no frame of reference to see if the video frame rate has been tampered with. This is the only potential speedhack out there, if the video is not altered then we're talking at least 300%+ speed increase.
The other issue with the speedhack idea, as recently mentioned, is that there are a couple of abilities that increase speed. So when you see the guy who is consistently moving 10% faster than you, they aren't trying to be sneaky and hacking, they're using an ability.
Next, there is an issue with lag, auto-run, and movement commands. I've personally tested this with a friend in the same town using the same ISP with the same bandwidth and almost identical latency (identical routing). Most of the time we move at almost exactly the same speed, on average- for short distances often one or the other arrives first but over a long straight run it evens out. However, we've noticed that sometimes one of us seems to always move a little faster- and we discovered it happens when one person uses auto-run and the other just holds down the forward key. My theory (completely unproven) is that auto-run sets a flag on the server, but holding the movement key has to re-send your actions periodically which might result in some of your movement being missed due to server lag or packet loss.
But just to note, while I've seen people moving slightly faster, maybe up to 30% even, I've never seen anybody hauling *** at the rate of speed in the 'video'.
Second, let's talk zoom. I haven't seen any video demonstrating this hack, however I have noticed that if you go into 1st person you can use the mouse wheel to 'zoom' in and out. So I'm thinking this is yet another actual game-feature being disguised as a 'hack' to fool the unwary.
Third, let's talk about warp/teleport hacks. Now I know it's possible to hack the game and go places you shouldn't be able to, but I've not seen such a hack work while online. Or in other words, I've seen hacks that allow you to "play" the game offline, but all you see are the NPC's (no spawns) and most of the mechanics don't work. One magazine used such a hack to get some screenshots of off-limit areas during open beta, but the hack doesn't do anything while playing online, it's just a way to load up the engine and view the game world data that is saved locally. I suspect that this is the same thing that was done to advertise the 'teleport' hack, part of the same video I mention above.
As for bots, well ya people are using them. But there really isn't a lot of RMT going on (yet) and the bots really don't work very well at all. They get by ok for farming mobs, but as mentioned they aren't very effective since they currently don't have any way to monopolize spawns. But as for fishing, mining, and harvesting, the bots just plain suck; they really don't deal well with the mini-games you play in order to harvest (they suck at crafting as well for the same reason). With mining and harvesting they have an especially hard time since there is a limit to how much you can farm a spot, and the spots tend to move around which can mean a bot that sits idle for hours or days.
But don't get too worried about hacking. Anything that breaks the game-rules, like teleporting vast distances without using Anima, or moving at 10 times the maximum game-allowable speed, can (or should) get easily caught with log-file examination. I think we haven't seen the ban-hammer much because of the free trial period- SE will wait until pay-to-play and then start canning the accounts after they've gotten at least one or two payments out of them. As long as the devs pay attention and learn from failures in other games, botting shouldn't cause too much of a problem over the long run.
