I see on YouTube some people running their cars without a blow off valve. What's the pros and cons?

I believe it was the toyota celica alltrack. It did come factory with no blow off/ diverter valve. I think it was running running like 5 lbs of boost, I dont know what turbo but I'm sure it was tiny.
