I agree some people think too fast people who don't respond are bots, but the "all chat off"-excuse is pretty lame. Except for HUGE popular people like zezima in the old days, people who do gwd bosses or jad and need full concentration etc there are barely people who use the all chat off function. Bots do turn that on, but only to have later on an excuse they didn't respond when you talked. I for myself see no chatting as a first hint someone's a bot. Then I check his click patern, most bots have a "constant" delay between clicks, though not all have. Another thing to see for instance fm bots is to mess up their lines and see what they do. Fm bots at FOG just start a new line over and over again if their line is messed, even when they only have 1 log in their inventory left. Mining guild bots are very easy to detect as when they run to the stairs, they never go them up by 1 click but they always run 1 diagonal square away from the stairs, then click the stairs to go up. A last thing I use to check if someone's a bot if he doesn't respond, though his clicking looks human is following him for like 5 minutes. Don't tell me a human wouldn't think it's weird if he sees another player following him all the time. In rare occasions, the suspected bot then says What? but most of them don't respond which gives me last proof they're a bot :P
