glassdoor got sued by employers, that were getting afraid of users/former employees calling out thier shady/unethical business practices, this include thier hiring methods. thats why astroturf the reviews, also requiring a datamining account to accessit. most other sites equally got scared and did the same thing. Indeed got rid of thier forums(mostly did the same thing calling out certain jobs, which ones are using ghost jobs,etc) around the time glassdoor started working in chaoots with the companies.
