Reminds me many years ago I was playing online poker. The site I was on did this special anniversary giveaway thing. Every million hands or so, there would be a massive (in relative terms) jackpot. If you win the hand, you get the jackpot. It was so large, that you should never fold any hand, at all. (At these microstakes, normally a big hand was $5. These were like $300, so risking your whole stack of $2 was totally worth it).

At the start of the hand, the rules were announced, and there was a very long wait (10-20 minutes), so everyone had a lot of time to process what was going on.

I was dealt into two of these hands. In one, I raised all in and everyone folded. In another, someone else did this, and everyone except me folded.

That convinced me that almost everyone was a bot. There was no rational explanation for this behaviour.

Once they get you hooked, they can match you with the other whales. Until then it's just training your reponses even when it costs them 300 fluffmarks.
