I've done this many times when I don't feel like playing but still want resources. Although you can tell that I'm not a bot by looking at my search info and see my levels. I would recommend that you start with that if you suspect someone is botting. If they are just a DoL (1 job) and nothing else, then that's far too suspicious. DoH is a bit different as people can have alts with only DoH for specialization since you can only have 3 per character.
