To correct everyone assuming its a Decay hack... seriously are you listening to yourselfs? Decay is SERVER SIDED. Every single decay instance is server handled there is no possibility that a client can control it all they get from it is the decay damage for objects from it.
It's basically a giant AOE of a melee weapon, it's possible because if you didn't notice appearntly damage packets aren't checked by the server at all so that's the most likely candidate. Also these hacks are actual hacks, they're not done by the script kiddies as you may tell because if it was purchasable of public knowledge every server would of been wiped.
Also I don't think garry would rollback the server due to the lag that's starting to occur it'd be much better for him to do a complete wipe.
Ignorance is bliss, every single ban would need hard evidence because most of this can be fought against by the player if they don't have anything. You could just as easily claim any Admin they hire is BIAS. Most common hacks such as Speed Hacking and Jump Hacking are detected and aimbot can be hard too prove. I've gotten around six chain headsets with a sniper and hackusated of aimbot and even banned from some servers because of it.
In the end guess what? They ARE pixels, thats like trying to think of whats the point of playing in any game?
I've played Runescape and must of sunken atleast 2,500 hours easily along with my friends and times changed, that game I no longer find any fun in playing and do I considered it wasted? nope. It doesn't matter when it happens the point of the game is to have FUN if you're putting in even more weeks of grinding/raiding if this wants to make you quit go and take a break and come back to this game in a few months and have some more fun.
I wouldn't mind a wipe. The official servers are VERY over due for one. There has been multiple posts expressing the want/need for wipes.
Sorry we don't know the technical stuff. All we know is lots of stuff was destroyed by one person.
