I have returned to my country after [one negative experience as a postdoc][1] in China.
In short, I was hired based on false salary & funding expectations supported by shady vague contracts written in Chinese. I stayed until the end as to escape a raging crisis at home. 

Now I am back home, among long-date colleagues & collaborators. A large international conference in our field of study starts today. The very same PIs who lured me into their trap are coming, *now in my country*, **actively seeking for new candidates**. Surely they expect me to treat them politely, coldly at best. These people owe me a lot of money, plus stolen time and project ideas.

I think they expect me to stay nice and quiet for fear of getting bad recommendations and in the hopes of perhaps getting paid/compensated in the future. The culture here is certainly different from what they expect. *In just few hour*s I will meet them at the conference hall, for the opening.

I am revolted. At least in my country, LoRs are not required for getting jobs, and I do not think they're too influential outside of their institutions. 

**Should I openly expose them**? **Or would that just label me as some begrudged nuthead?**

There is one special roundtable about work ethics included, and I am thinking of approaching the organisation about this. Any suggestions, ideas on this, would be appreciated.

P.S. This is *not* in the US.
