Are you saying this from experience?Its depends on your spamming. With in 1/2 days or more.
Most people don't report tweets though.If you send the same link to random people it can get shut down in 10 minutes. If you don't believe me, I dare you to spam me on Twitter.
1. How many people and tweets were you following and favoriting per day?You can easily post 25-30 tweets with links per day without getting banned. Iv'e posted up to 50 spam tweets. The only thing that they seem to look at is the hashtags. If you spam 5 or 10 tweets with links that contain a trending hashtag you get banned. Try not to use hashtags and you should be fine.
I only follow. I don't favorite. Its ussually 500-600.1. How many people and tweets were you following and favoriting per day?
2. Will i get banned if use hashtags relevant to my niche?

I don't think you will get banned if you use relevant hashtags. It has only happened to me when I used trending hashtags that had nothing to do with my niche.
It was the same web link. It don't really matter though because shortners only shorten a link once I think.Did you post the same web link?
was it shortened?
It totally depends on you
If you are within twitter limits account can run for longer period of time
