Doubt in Verbal Question

Hi Greg,
When I was solving this verbal question, I thought the answer should be inhibiting and forbidding. I am not able to understand why forbidding is not the answer.

Can you please elaborate on it a bit more; like how did u tackle it ; what was the reason for eliminating other answer choices etc…

I thought that high price would be required for vendors to get enough revenue , so as stop people from frequently using the website and taking it for granted

And for that forbidding and inhibiting looked good for me . I did not understand why instead of forbidding, bridling is used?
