This is a blatant misuse of the blacklist concept.

If you were cheated out of money and worked for more hours than your contract stipulated, THAT is when you blacklist a school. Or when a school lies to your face about what your job will be about i.e. promising you a high school administrative position but instead have you teaching kindergarten students. Nothing you wrote in your "review" came close to supporting such a conclusion.

Disagreeing with how a school operates the business side of things is a matter of personal opinion that should be irrelevant for a lot of teachers. What a professional and experienced teacher should care about is his/her salary, teaching hours, and benefits. Schools hire teachers to teach (preposterous, I know), not to become best buddies with the students. Befriending students is the byproduct of an enriching and rewarding classroom environment carefully crafted by the teacher. It is not something you forcefully and artificially construct by appealing to the student's five senses of teenage angst and rebel against the school with them. Not to mention students have this thing called parents who are perfectly capable of making the decision on whether to send their kids to the school or not. Your attitude is extremely condescending, as you assumed parents have no clue what is happening at the school and are instead lied to constantly. The truth is the parents are well informed about what is happening and the vast majority either supports the school or have no opinion on the matter.

Finally, please fix your grammar and syntax mistakes. You make foreign teachers in Taiwan look awful and unprofessional.
