Will I get banned for this on twitter?

[Nobody]

I have a lot of celebrities following me on twitter and so I really REALLY don't want to lose my account.
I signed up for this thing to get more twitter followers for free, what I didn't know is that it makes you automatically follow like 80 people first.
So now I'm following 80 more people and I was only following about 30 people who were friends in real life or celebrities I have met.
My timeline is filling up with random useless tweets from these people I don't want to be following and I cant find the tweets from my friends.
I have 2,455 followers and I don't want to lose this account, will I get suspended or banned if I unfollow all 80 of these useless people it made me follow?
or should I wait a week or so?

The worst part is it only gave me about 20 more followers so I'm kinda regretting doing it.
