just wanted to say there is a new hack out there which is basically really really hard to spot. I quit mc so I dont know anything bout this It is killaura but its something called high hits per second just watch out for it
It's not new, it's a hack that works on some 1.6 clients but the coding for 1.7+ was too complex for it. Looks like someone managed to get around the problem. With a single person, you could crit someone in maxed enchanted armour and a gapple, without even using a strength potion. It was terrifying in the early factions days
