February 1, 201411 yr You get hit 0's or 1's once or twice to check if you escape the combat for some time even if there isn't anything that could hit you. There should be a check that if there is NPCs that are hitting you before you run out of the combat. If you fail at this many times, you will most likely get banned. I've experienced this many times while babysitting the bots. Edited February 1, 201411 yr by OSM
February 1, 201411 yr Post a screenshot next time you see this occur please? They could implement a Combat Solver, which runs if you're being damaged.
February 1, 201411 yr I mean theoretically this is a good way to detect bots, though i'd love to see some proof.
February 1, 201411 yr there are hidden randoms actually, but only for people who jagex think is suspicious.
