I am going to check how it looks in the logs when i go through lots of story choices. Have checked before if you can see in the logs in the admin panel if someone is boting, and I could not see anything. But I don't think i looked so much at the logs timestamps.
Have checked it now. There is no specifik log for story mode, but you can see what you have done in other logs, such as the gold log. There it says you got the gold from stories, and it shows what time you did it in, and include seconds. I had my bot delay at 1 and in the logs there was a delay of minimun 1 second for me.
That means, it could be detectable through the time, but you can't be sure if someone used a bot or not, in my opinion. I believe it is possible to progress that fast manually if you have a fast enough computer and internet speed.
Sorry that I wasn't more observant of that before. Did check it but completeley missed that detail. But if you set the delay to about 5 seconds or something like that it should be no problem, as you can easily do it manually in that time.
