Ok as Unorclan mentioned that you know if they are a player who loves that skill. Well i ahd a low aco[bleep] that had like 40 fishing, but..... If you want to tell if they are a marcoer. Try to speak to them, if they do not respond, then they are a bot. If they speak then yes, also odd names such as 435435243 or lolt039338tty, etc. They are names that are to hard for one person to remember, you can also learn from that. As much as we all hate bots, we cannot stop them, unless jagex puts a block on bots, which would be hard to do. best bet is to try and ignore them, report them 1-2 times if needed, then let it be. We cannot stop them b/c some players are just to lazy and sad to enjoy the game themselves, and like to take the fun out of it. That just makes them lower. As i said just try to ignore them.
