I'm thinking of making a new email account just to leave an anonymous bad review where I used to work
Isn't that extreme? Is there something about your former company you didn't like?
Yes there's a lot of bigoted people who uses homophobic slurs to criticize employees.
That sounds like a really toxic work environment and I'm glad you got out of there!  It's good of you to want to draw attention to something like that.
I'm letting the world know. It will be hard not to think about how toxic it is- in a good way.
Thank you for taking initiative, you might be sparking a movement where other people will be comfortable to speak out. Everyone deserves a welcoming and safe place to work. I believe they would be so thankful for your actions.
