It depends on the questions - I don't feel like I've often gotten bad answers when I've asked and I know I try my hardest to be as honest as possible when candidates ask me hard questions about my position.
If I get red flagged for asking about their on-call policies or office-work plans or how they're handling the position/responsibilities that I would be taking on, then that seems like a bullet dodged? It's not like I'm expecting people to ask "So tell me about why you hate your manager" or "When was the last time you fired someone". You can ask probing but polite questions that give you information without having people tell you the sort of angry gossip you get on Glassdoor.
Obviously, tailor this to how desperate you are. If you want absolutely zero chance anyone will reject you for any reason, then you should be asking the most fluffy questions you can. I certainly don't reject people for asking those questions. I just find it a weird signal when someone seemingly doesn't even want to pretend to care about content, structure, and culture of the job they're interviewing for.
