I would totally cancel my account.
Here is the severity of "cheats" in my eyes, from worst to "grey area".
1) Scripting and speed hacks related to PvP. These really go without saying. They are an absolute no no. There is no point to playing this game if those exist and/or are allowed
2) Scripted resource gathering. Think of a script where you recall all over place in your LRC suit to mine, and then recall back to your house to smelt and box your ingots. This is terrible. Another example is people that have a script that logs into their bod account(s) and get bods every hour on five or more characters. It needs to be met with severe punishment. Banning. It totally horks the economy. And provides easy money for gold selling web sites.
Those are the main two that need to go.
3) Unattended non-scripted resource gathering. This is somewhat different, but not really any less severe. Think of someone looping a Fishing macro at Brit docks or something like that. Not really that big of a deal. It's something you could do attended, but umm.. *yawn* They are probably doing it to gain skill... which leads me to my next point.
4) Unattended macroing of skills. Really, to be very honest, this is very tricky for me. I'll come right out and say I've been suspended for macroing Hiding in my house. At first I was pretty pissed, but that's the rules. Needless to say, I don't mess around with this anymore. But really? Macroing Hiding is that big of a deal? I don't think so. I'm ok with this to be honest. I don't care what the skill is.
5) Using 3rd party programs to enhance your experience, without giving an advantage. In this situation, your definition of "advantage" is what really matters. You have things that will auto-open doors, auto-open corpses, help you with buying and selling from vendors, allow you to increase your screen resolution to unsupported sizes, etc..., etc... I think these should 100% be allowed, no questions asked.
