Founder of http://Accelerat.io here. This is exactly why we started our project, we hear a lot of these stories of second and third tier accelerators doing these kinds of shenanigans.

Would love to put up the accelerator you're talking about with clear information so future entrepreneurs applying can know about this upfront.

If you contact me at hello at accelerat.io I'll set it up for you. Rest assured, it will all be 100% anonymous.

The transparency for accelerators is terrible now. Every founder presumes that the new accelerators are at least trying to follow the template of the best accelerators. Surprisingly often that's not the case whatsoever, down to the smallest meaningless details.

A good start might be submitting those details to (http://accelerat.io/). They seem to be tracking this.
