Anecdotally, Glassdoor will often remove negative reviews for paying employers by giving flimsy excuses like "They are against the 'Community Guidelines'" (something that's so broad it's impossible to hold them to specifics). The "features" they advertise for paying employers are all above-the-board though.
Adding another anecdote, I worked for a company which paid Glassdoor to remove a bunch of negative reviews. The score jumped from 2 to 4 overnight and a bunch of well-written negative reviews disappeared.
Can confirm. Old employer started asking employees to post positive reviews when their rating tanked following a series of poorly integrated acquisitions
