I need help with Twitter ? :(?

[YaDunkno 2K11]

Ok i opened a Twitter account up like last week for my website & my obvious first reaction to do is get as many followers as i can so i typed into google free fast followers then i found this website which claimed they could get 100 follwers an hour so i logged into the website with my twitter account details and it did work but then the next thing i know Twitter had suspended my account but luckily i made them un suspend my account so when they did i changed my password on ny Twitter account but now the problem is when i un follow everyone on my twitter account they all go but then suddenly it says i am following someone i never followed and dont even know so does anyone know why its happening ?
