Safety and perspective

I was asking in text to image for "XXX in Perspective with two vanishing points", that means 30 in roman numbers. And the answer was: 

Can't load. We encountered a safety issue with this image. Please try again.

Whan i replace 30 with 10, i.e. single X I've got a picture. 

I dont think that number 30 is 3 times more dangerous than 10. 

And last but not least - system has no idea what perspective with two vanishing points means. One picture was a divergent perspective, one flat two axis symetry, one flat multiaxial symetry and one no symetry
